Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

Still no luck. Tried it on Arch and fresh Ubuntu. Checked settings and
volume level. There is still no input signal on internal mic. :(

Hi,

I tried setting options snd-hda-
  intel model=alc255-acer, and it worked for me after a reboot.

Let me know if it works for anyone else

[Kreaninw]

@JackyOhh and @dharman

I didn't do anything at all. It just works out of the box for me.
However, you might try to increase the mic volume with PulseAudio Volume
Control.

And now, I have another problem (which I had never tested it before),
there is no audio output through HDMI. I reported the bug here:
https://bugzilla.kernel.org/show_bug.cgi?id=214923

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[JackyOhh]

No luck here. I booted a fresh Ubuntu 21.10 from USB. Although internal mic 
showed up, no sound was recognized on Acer Aspire VN7-592G. 
@Kreaninw Did you change anything in /etc/modprobe.d/alsa-base.conf or 
elsewhere?

  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Kreaninw]

Tried this again on Ubuntu 21.04. There is still no sound out of the
box.

I then compiled the alsa-topology-conf as suggested here:
https://gist.github.com/crojewsk/4e6382bfb0dbfaaf60513174211f29cb
#enabling-the-configuration

And enabled the options snd_intel_dspcfg dsp_driver=2.

But still no luck. I believe that I will have to do the NHLT overriding
for it to work. However, that's beyond my ability. The page suggested
that we should ask Intel developers for help to obtain the correct NHLT
binary.

  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  cat /proc/asound/cards:

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Kreaninw]

I'm using Acer Swift SF514-52T (Intel 8th Gen Core i5) on Ubuntu 20.10 -
Linux kernel 5.8.

The default configuration has no sound working at all. I believe it uses
the SOF driver (I could be wrong) which doesn't support the Kaby Lake
platform, as the issues for supporting this platform have been closed (
https://github.com/thesofproject/sof/issues/1899 ). And the proposed
workaround to support this platform have been discarded also (
https://github.com/thesofproject/sof/issues/2256 ). Therefore installing
the latest version or any version of the SOF driver will not solve the
issue.

Force enable the HDA driver (snd_hda_intel) in /etc/modprobe.d/alsa-
base.conf with options snd-intel-dspcfg dsp_driver=1, the sound output
works fine but the internal mic (DMIC) doesn't work. And I believe we're
moving to the SOF driver which doesn't support my device. Therefore I
don't expect any fix will be done in HDA driver.

I tried to use Intel's SST driver as it's the only solution left. I
enabled it with options snd-intel-dspcfg dsp_driver=2 but both the sound
output and the internal mic (DMIC) don't work.

I also report this bug in
https://bugzilla.kernel.org/show_bug.cgi?id=201251

Here is my alsa-info (with options snd-intel-dspcfg dsp_driver=2): http
://alsa-project.org/db/?f=db024ae3c924d318bda813f73c73e76df36bbca2

I attached my full dmesg also.

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Dominik]

It also affects Linux Mint 19.3. 
I had problems with audio also, so i had to add two lines:

echo "options snd-hda-intel dmic_detect=0" | sudo tee -a 
/etc/modprobe.d/alsa-base.conf
echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf

After executing these two commands audio is present again but still no
success with internal microphone. Fortunately i have detachable
microphone in my Creative Fatality headphones so after i have inserted
this microphone in microphone socket, microphone has appeared inside
pavucontrol and i am now able to record voice using this site: https
://online-voice-recorder.com/pl/ for example.

I have noticed that there are more discussions about this problem:
- https://online-voice-recorder.com/pl/
- https://github.com/thesofproject/linux/issues/1877

P.S. I have also tried to manually remap pins using: hdajackretask but
with no success.

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Gordon Lack]

I had a problem with a *missing* internal microphone today (well, I spotted it 
today - probably been like this for ages...).
Note that this was PulseAudio saying that there were no input devices.

The problem (as I eventually spotted) was that I'd set the Profile to be
Analgue Stereo Output (under Configuration in PA Volume Control).

Setting this to Analogue Stereo Duplex made the internal mic show up.

Might not be the problem for most people, but you never know.
I did notice that if I plugged in an *external* mic the Profile switched to 
Duplex automatically.

[sahil]

I have Dell Inspiron 5591 and installed Ubuntu 18.04. 
Internal Mic not working. I have tried to add jack 0x12 but it has only white 
noise.
Also added 'options snd-hda-intel model=dell-headset-multi' in also 
configuration but no luck.
If anyone get to resolve this please share your findings.

@Hui Wang
Is it possible to have the dkms driver as a workaround also for other kernel 
versions?

  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

This also affects the current ubuntu version (dingo). Is there a patch
in some newer kernel? Many people have to work remotely nowadays, so it
may be reasonable to mark this bug with higher priority?

[Hui Wang]

According to #82, that deb was not installed successfully.

This is probably because you enabled secure boot in the BIOS or boot the
signed kernel. Could you change to use the unsigned kernel (#79), maybe
disable the secure boot in the BIOS, then you could load the unsigned
kernel.

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.019164] snd_hda_intel :00:1f.3: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])
  [3.047505] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC255:

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

[Kreaninw]

@Hui Wang

Are you sure that it wasn't installed? As you can see in my attached
screenshot, I'm using your oem-audio-hda-daily-dkms.

And I can't install an unsigned kernel too, as I'm using UEFI laptop, it
won't let me install the unsigned kernel.

According to #27, the deb was not installed too, let me build a kernel,
then you could test the kernel instead of this deb.

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Hui Wang]

According to the alsa-info.txt in the #73, the fix in the dkms of #72
doesn't apply to your machine.

Did you install the dkms of #72 successfully?

please run 'dkms status' to check if oem-audio-hda-daily-dkm is
installed or not.

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-

  jack, which works fine when I plug an external microphone in it.

  Here's some info:

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  One problem is that I can't find any model options (options snd-hda-

  (ALC255), I suppose this issue is relatively new.

  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

[Allan]

Same problem here with Acer Aspire VN7-792G and ALC255. Internal mic not
detected and hdajackretask not working.

This model also has a separate mic-jack and a headphone-jack and an
internal mic. The internal mic isn't detected and not working.

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.019164] snd_hda_intel :00:1f.3: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])
  [3.047505] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC255:

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Jeff Shee]

Same problem here. My laptop is Acer Aspire VN7-572G.
Still don't have any fix for this? Almost 2 years since the bug been reported...

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Andre Mack]

For me the same error: the internal microphone is not recognized. I have
an Acer Aspire VN7-572G-56VP with ALS255.

An external headset works when I write in the file: 
'/etc/modprobe.d/alsa-base.conf' the following entries: 
'options snd-hda-intel model = dell-headset-multi'

  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  One problem is that I can't find any model options (options snd-hda-

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Patrick Monnerat]

I'm the proud owner of a Acer Aspire VN7-792G Nitro and I'm encountering the 
same internal microphone problem.
I've carefully read all the posts above and I focused on the link in comment 
#13.
One thing seems to me pretty sure: snd_soc_skl won't detect hardware on the 
above mentioned machine because the later has Intel SST named "Sunrise Point-H" 
(ID: 8086:A170), which is not supported by the snd_soc_skl driver (only Sunrise 
Point-LP 8086:9D70 is listed). I'm pretty convinced an entry for Sunrise 
Point-H must be added to skylake/skl.c.
I've tried locally updating as above: the snd_soc_skl driver then recognizes 
the device. However this is not sufficient: there are probably additional 
things to do to make it work... or maybe this is a conflict with snd_hda_intel 
??? This is out of my current knowledge.
I hope this helps.

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[ntvf]

I also can't get mic work on my Acer Aspire VN7-592G with ALC255.
Microphone are visible with some options for snd-hda-intel (such as 
laptop-amic, laptop-amic, dell-headset-multi), but it record just a white noise.

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.019164] snd_hda_intel :00:1f.3: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

[Desktop-packages] [Bug 1523100] Re: Alsa not detecting internal microphone [ALC255] (Realtek)

[Roger Norton]

This bug also appears to affect my acer aspire VN7 792G.  I am unable to
use the internal stereo microphones, for skype for example, and they are
not shown on the input tab of the sound section of the system settings.
Please notify me when there is a fix to this bug.

[DarKy]

Dear developers, please, give us a hint when this issue will be solved?
There is no workaround and no assigned person. I understand that you have much 
more important issues at hand but at least some time frame would be useful for 
us, users.

Thanks in advance.

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.019164] snd_hda_intel :00:1f.3: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.

  Here's some info:

  lspci | grep -I audio:

  00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H
  HD Audio (rev 31)

  cat /proc/asound/cards:

  0 [PCH]: HDA-Intel - HDA Intel PCH
  HDA Intel PCH at 0x8432 irq 128

  And a clip from dmesg | grep snd:

  [3.019164] snd_hda_intel :00:1f.3: bound :00:02.0 (ops 
i915_audio_component_bind_ops [i915])

  [3.047514] snd_hda_codec_realtek hdaudioC0D0:  Mic=0x1a

  One problem is that I can't find any model options (options snd-hda-
  intel model=something) or other parameters for the card's model
  (ALC255), I suppose this issue is relatively new.

Title:
  Alsa not detecting internal microphone [ALC255] (Realtek)

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  I've just installed Ubuntu 16.04 alongside Windows 10 on a 64bit Acer
  Aspire VN7-792G and noticed, that the internal microphone doesn't
  work. The computer has been released a couple of months ago and it's
  Intel Skylake -based with a Sunrise Point -based motherboard.

  INFO: The problem exists in Ubuntu 15.10 too, only microphone jack
  detected. Currently using Ubuntu 16.04 for proper hardware support.

  Alsa reports the audio device to be:

  Card: HDA Intel PCH
  Chip: Intel Skylake HDMI

  The speakers are working fine, but both alsamixer and pavucontrol
  (Pulseaudio Volume Control) raport the unplugged external microphone
  connector as the only sound input.

  I have tried many of the alsa model configurations (options snd-hda-
  intel model=something) without success, alsa finds only the microphone
  jack, which works fine when I plug an external microphone in it.
