[Touch-packages] [Bug 1801540]

2020-04-20 Thread adam.reichold
The problem still seems to affect Raven Ridge ([1022:15e3] in a HP
ProBook 455R G6) using kernel version 5.6.4.

Disabling the SNDRV_PCM_INFO_BATCH workaround subjectively improves
capture quality using `parecord` but it is not really usable either way.

2019-10-28 Thread bkrippner
Confirming this for ALC887-VD Analog [ALC887-VD Analog]

Audio device [0403]: Advanced Micro Devices, Inc. [AMD] FCH Azalia
Controller [1022:780d] (rev 01)

Crackling seems to only go away when mix is set to lower than 10% in
pulseaudio. If the device oversaturates it seems to try to lower the
volume and starts to crackle for a while making it unusable to record or
talk for a long time. This has been around for a long time now.

It seems there is already a patch but im kinda worried by the version
number. 5.3.x seems pretty far away from stable
releases(5.0.0-27-generic)?

The second patch cited in my previous post is necessary now (under
5.3.5, not sure about the previous kernel versions); besides the small
crackles when changing volumes, the acquisition from the microphone
under load (compilation, for example) sometimes becomes extremely low
quality (like if the sample rate is changing randomly and often the
audio is clipping). Applying the patch only on the capture stream
completely fix the issue, no crackles when changing volume and no issue
when acquiring audio with Discord under load.

Steam still shows random audio stutters while acquiring for a minute and
a bit of delay, so that is still unchanged, unfortunately.

Will this patch be in the future stable Linux releases ? I mean if Linux 5.3.1 
will have this patch by default.
It is curiosity because I don't know how Linux versions works

With the standard flags, Discord is perfect, Steam has stutters for the
first minute and a bit of delay (500 ms).

With the batch flag only on the capture stream, Steam is perfect,
Discord has delayed audio.

With the batch flag only on the playback stream, same thing with both of
them (first case).

2019-09-06 Thread rodomar705
Following my previous post, disabling the batch flag on both streams
(patch 3 from comment 269), Steam is perfect, Discord is lagged again
while acquiring.

With the second patch from the comment 269, same identical problem
without the patch (Discord perfect, Steam crackling for the first minute
+ audio slightly delayed). However when changing volume there was a
little bit of distortion on the output audio (extremely small, but still
audible, especially on high volumes), but it seems that using the
workaround only on acquisition seems to have removed that small issue.
If someone here had the same problem when changing volume, please try
patch n.2 and report back.

It seems that we can't have both working together simultaneously on my
end. The default workaround is still the best option on my system, for
now.

2019-09-02 Thread lukycrociato
How does position_fix = 6 (the FIFO that the patch adds) work?

Because when I add it, makes the system (only for GNOME) laggy when using 
Discord, exacly like before as I said in comment 86 
https://bugzilla.kernel.org/show_bug.cgi?id=195303#c86
But this time obviously the mic capture is fine.

Still in all those cases, the playback is distorted/robotic for a minute
or so.

But I remember the voice to be robotic months ago like this only when
using Arch Linux??? (So an updated kernel, instead of the Ubuntu LTS I
use right now) but since I used an USB card since now, I don't remember
how the playback was working previously, I'm sure the microphone capture
was still bad before this patch solved it

2019-09-02 Thread rodomar705
I confirm that both version of the second patch work. On playback I had
only some minor issues when the stream was starting, but after enabling
the playback patch, they disappeared too.

Without tsched=0 and without the playback patch, acquisition work
perfectly fine, but not the output, is delayed in time again.

Forgot to test it without tsched and playback and data from fifo
directly and not from VIA register, but I can recompile it if it is
needed.

I think that both patches are needed, even if my playback issue wasn't
that problematic.

Testing n.4 shortly.

Thanks a ton for your work.

I know it's not but just wanted to mention it since i can't find a bug
report about it plus i am sure the same people that are affected by
crackled sound capture are affected by this one as well

Before filling a bug in the kernel bugzilla you should check if that
happens with Alsa only

Thanks.  The problem with playback indicates that the delay correction
isn't good for playback but only for capture.

Below is yet another revised patch.  It corrects the position report
only for the capture, but takes the FIFO delay into account, too.

Discord being robotic can happen on functional audio cards as well, i
for example had it on my laptop in the past. When subject to the real
bug this does not clear up at all and will remain an issue for a while.
The non related bug in discord itself i can usually get rid off by
opening and closing other applications like my webbrowser and yes it
does clear up on its own as well.

Actually, scratch that. I never tried the mic port until today (didn't
have a mic). The crackling is present as reported by others.


In 5.2.9, there is a different kind of distortion when using a usb webcam's mic 
for input + onboard sound card for output on steam voice chat.
This new distortion issue wasn't present in 5.2.8 with webcam mic.

The stutters remains only for one minute after activating the webrtc
stream on Steam, afterwards the audio clears up and, besides a long
delay of around 1/2 of a second, the audio is clear.

Hi, I tested this patch and it seems to be working fine.

1) Test made at https://webcammictest.com/check-microphone.html, it
works fine as the previous patch. This is a self hear test, everything
works perfectly

2) Second test was made opening discord and using the builtin mic test,
which also has a builtin self hear test.

But, this time the output sound crackled for the first 3/4 seconds, then
it was working fine. Unlike the previous patch where it was still
present after that amount of time

Kernel 5.2.5.

Distortion/crackled sound in steam voice chat started with kernel 5.2.9.
Differently distorted sound in discord web - parts of voice is chopped off 
every half second or so, and a large lag - 1 second or so.

Everything works fine in 5.2.8.

OK, that's good to know.

And how is the application set up?  Does it run over PulseAudio backend
or accesses directly ALSA devices?

The BATCH workaround was needed for PulseAudio.  Does any other
application using PulseAudio (wrt capture) work on your device?

And it'd be strange if this setup change makes any difference on USB
webcam behavior.  If so, it must be a bug in PulseAudio.

I notice the following in the log with patch 7:
Also, I don't know if it's expected but enabling 'mic boost' produces a lot of 
noise.

That's mostly harmless chats from PA unless you hear anything obvious
due to this.  The noise by the mic boost is also normal.  It's rather a
codec side problem and the hardware implementation itself.

Tried with 5.3-rc6

Problem: Distorted sound with steam voice chat with 1022:1487.

# 3 Worked for steam voice chat but unfortunately not in game eg.
Counter-Strike: Global Offensive

Discord is mic is now distorted unless I set tsched=0 but if I set that
then Steam chat is distorted.

I will check the above patch shortly

Everything on PulseAudio.

Well, I've also tried arecord, gnome-sound-recorder.
These and Skype work with and without the BATCH workaround.

Steam and Discord have severe issues with the workaround.

The patch seems to trigger the issue as long as the device is in use -
even if just for playback.

With the workaround, if I use HDMI output and USB webcam, the sound is OK (i.e, 
this device not in use).
Sound card's line-out + any input source causes problem.

So with patch 7, but tsched=1 (ie. not the part with |= BATCH included)
I get the following:

Only test idea 1: crackling
1+2: no crackling but playback skips when start/stop recording
2: no crackling but playback skips when start/stop recording

I retested patch 2 and realized I also have that behavior there: no
crackling but playback skips when start/stop recording.

Yea, same here on B450/ALC892 with tsched enabled (which AFAIK the batch
flag is the same of disabling tsched on the kernel side of things).
Other chipsets instead seems to behave differently (if it is the front
end and not the backend, the Realtek codec).

Very weird.

Then I have no better idea for now than disabling the tsched on PA.

The patch below is a combination of the former patch (modified no.6) and
the flag set to enforce tsched=0.  This should work without changing PA
config.

Let me know if this works better.  If the things work reasonably enough,
I'm going to push it to upstream.

2019-09-02 Thread henk717
Did some tests using the AUR package snd_hda_intel-alc1220-dkms (Seems to be 
Patch 2) on the 1022:1457 ALC1220 (X370 Pro Carbon motherboard).
Using the default settings i no longer hear the robotic echo issues in my 
microphone recordings and i am able to get good recordings with Audacity. 
tsched=0 seems to have feint audio issues which are similar to my best case 
scenario without the patch. It is hard to hear and could be a tsched=0 only 
issue.

However more worryingly i was able to reproduce my former Audacity
"Dolphin speed" issue where it records way faster than it should. While
not present by default this happens after i use pulseaudio -k and then
try to use Audacity. This does not happen on my laptop with an Intel
Motherboard and connexant audio chip indicating it is still driver
related. The effect happens both on the "pulse" microphone and on the
direct microphone when selected.

Perhaps this is already resolved in the future patches, but i found this
an easy to replicate testing scenario to see if underlying bugs are
present.

Is this with tsched=0?  I wonder why PA gets the position information so
often.  Without tsched change, PA should access to the hardware much
less frequently.

In anyway, one another interesting experiment is to reduce the max

2019-09-02 Thread lukycrociato
Another update, on kernel 4.19.63 with position_fix=3 the output
crackling lasts 10 seconds. So to me it looks like that parameter is
somehow "applied" to the 5.2.5 kernel by default??

Compiling a *4 in the parameters, I'll report back shortly.

Yes, the only clean audio stream from PA and arecord was with the define
enabled in the source code.

If it doesen't change, i'll post a trace from the codec.

Forgot to test with aplay without PA with the define disabled, however
the acquired audio with PulseAudio was bad, like "low quality" (and the
output was delayed as before). Using arecord (but not with PA disabled)
I was hearing again a little of crackling. With the define the audio was
perfect again with arecord (however only with PA disabled, I've tried to
use aplay in another terminal while using arecord, however the audio is
played back only when PA resumes; I'm not sure if this is something to
be expected), same thing with PA; however the output was delayed again
(when acquiring from PA). I've tested both S16 and S32 with the define
and pulseaudio disabled, no problem heard.

Also, try to increase the FIFO size defined there.  The current value (256

And, the delay happens even with the patch no.6?  Then my theory wasn't

[Touch-packages] [Bug 1801540]

2019-09-02 Thread lukycrociato
Hmm... I am noticing something strange between old and new kernels.

Without any patch applied, on the kernel 5.2.5 as Marco said, is working
fine after a couple of seconds (with or without position-fix=3) BUT a
little bit of sound distortion is present without the Iwai patch 6.

On older kernels than 5.2.5 like 4.19.63 the output issue "disappears"
with Iwai's patch after a minute, so it takes longer.

I think the issue is on the playback, because when I open Discord even
the system audio crackles. But still I'm not sure.

Is it possible newer kernels already have a partial workaround? I also
noticed the patch modifies less lines on 5.2.5.

I will certainly update it based on the reporters feedback from the different

It's hard to say whether it's a PA bug.  I still doubt it being some
inconsistent behavior of the driver, triggered only by some specific
condition PA hits.

Could you start PA with more verbosity and check whether PA complains
anything at starting capture?  It might be that the incorrect position
screws up PA, or something like that.

Neither did nothing, however the audio playback has no problem staying

So, it is a pulseaudio bug, if with arecord everything works correctly?

Number 4 works perfectly with tsched=0, but not without, stutters again
(delayed and crackled, probably from playback this time since you
mentioned it). I'll test patch v5 and report back.

OK, thanks.  Could you try another one below, too?

This should be a more correct way from API POV, passing the delay value
instead of the direct correction of the position.

[Touch-packages] [Bug 1801540]

2019-09-02 Thread tiwai
OK, that looks more promising.

Now I cooked two patches.  The first one is to simply apply the existing
VIA position fix to the AMD X370 platform (1022:1457).  This should work
like the test you've done now without any option.

The second one is an attempt with simpler position fix, just reducing
the fifo size.  Give this a try instead of the first patch.

There are adjustable knobs in the second patch, at azx_get_pos_amd()
function; the first one is whether to apply the correction to the
playback stream, too.  Since there was a report about the playback
stuttering, I enabled it here, but you can try to change it.  The second
knob is the fifo_size retrieval, whether to read from the same register
as VIA, or from the SD stream register.  The end result might be same,
but we need experiments.

Tested the posted patch from you, same issue. Tried to enable all DCAPS
flags (except SNOOP_MASK, SNOOP_ON, because I had used as a base the
patch in attachment 283955 that had already enabled SNOOP_TYPE(ATI); and
I915_COMPONENT (since I do not have an integrated Intel iGPU)) on the
codec specified inside line 20-47 in hda_controller.h, same issue
persists. I don't really know where to proceed. The only change is in
the noise frequency in time, it's more frequent or less, but the issue
is still there.

That's true, Steam Voice Chat has distortions/delays for 1 minute (but totally 
different than the usual like it was on Discord) 
Also, my voice has a much lower pitch too, and only for one minute. 

But I noticed this is happening on Discord too right when I join a
channel (or do a voice self test) for 2 seconds.

Not for me, on discord the audio is perfect. I still don't get where the

Ok thanks, I tested with discord and load-module module-loopback and it
works perfectly.

But with steam I tested my voice for the first minute of testing I sound
like a demon, and in valve games the mic is still distorted.

Any info I can provide?

So, if we delay the playback, too, it works, but it suffers from the

And you didn't get the same crackling mic input with patch no.2?
If so, there are still two differences:
- The patch2 calculates the delay from the register
- The patch2 applies the delay also for the playback

But the second point shouldn't influence on the recording quality.  Then
it's about the first point, and it can be changed like:

--- a/sound/pci/hda/hda_intel.c
+++ b/sound/pci/hda/hda_intel.c
@@ -866,8 +866,8 @@ static unsigned int azx_get_pos_fifo(struct azx *chip, 
struct azx_dev *azx_dev)

-   runtime->delay = AMD_FIFO_SIZE;
-   delay = frames_to_bytes(runtime, AMD_FIFO_SIZE);
+   delay = snd_hdac_stream_readw(azx_stream(azx_dev), SD_FIFOSIZE) + 1;
+   runtime->delay = bytes_to_frames(runtime, delay);
if (azx_dev->insufficient) {
if (pos < delay) {
delay = pos;


FWIW, the second point can be changed even more simply.

--- a/sound/pci/hda/hda_intel.c
+++ b/sound/pci/hda/hda_intel.c
@@ -878,7 +878,7 @@ static unsigned int azx_get_pos_fifo(struct azx *chip,

+   if (1 /*substream->stream == SNDRV_PCM_STREAM_CAPTURE*/) {

pos += azx_dev->core.bufsize;
pos -= delay;


Let us know if any of these (with/without the get_delay disablement) makes 
improvement.

In windows 10 the sound works fine.
I guess for X399 boards there is another issue. Non of the patches changed 
anything here. however, thanks!

2019-09-02 Thread tiwai
Basically patch 2 and 7 are essentially doing same wrt the position
report.  The latter uses the fixed FIFO size instead of reading the
register and it reports the actual delay size as well.  But the
difference is likely irrelevant with PA tsched problem Marco was seeing.

I guess PA would work without tsched hack even after removing the BATCH
flag hack from the patch7 on your machine.  I really have no idea what
triggers the problem and how.  More experiment results are appreciated.

In anyway, I already submitted the patch7 to upstream and merged now.
It'll be included in the next pull request to Linus, so likely landed in
5.3-rc4, then backported to stable trees afterward.

Patch 7 works very well here too AFAICT. Multiple playback streams and
recording  at the same time with PA.

With patch 2 you didn't have to disable tsched, but perhaps that was a
horrible hack in some other way.. ?

(And I can go pretty high on mic boost without very much noise).

That sounds like a different problem.  Especially a random noise
shouldn't be caused by the DMA position bug.  Try to clear the audio
setup once.

Does the audio work on any other OS at all?

OK, thanks.  Then it looks like that it's really the chip that stalls
the playback.  Around time 8102 until 8106, there is no playback
position update and proceed.  The same position is kept for 4 seconds by
some reason.

If this happens only at the full-duplex (capture and playback mixture)
trigger time, it might be in the SYNC register operation.  In that case,
a change like below might influence on the behavior.

No, this is with tsched removed from the parameter, so it should be one.
I’m forcing tsched to zero to not have the issue in PA, otherwise the
issue is not present.

If you like, I can post the same trace with tsched=0, if that will help
you narrow down the issue.

I’ll try the patch shortly,

Thanks again for your time,

Marco.

Title:
  Microphone distorted sound on ALC892/1220 on AMD chipsets

Status in Linux:
  Confirmed
Status in linux package in Ubuntu:
  Won't Fix
Status in pulseaudio package in Ubuntu:
  Won't Fix

Bug description:
  Not sure if I'll report this upstream but there is definitely an issue
  with microphone recording on my desktop, this is not happening on my
  laptop which has a different codec.

  Already tried all workarounds possible, no luck. Only with my desktop
  with this particular motherboard. No issues in Windows, the sound
  recorded in there is distorted and has some static and robotic tone on
  high-pitch.

> Codec trace for the audio output delay problem

Could you get the trace log for hda_controller, not hda?
(/sys/kernel/debug/tracing/events/hda_controller)

The former tracks the PCM events including the position report while the
latter tracks only CORB/RIRB communications (i.e. the verb execution).

Whoops, my mistake. Here is the correct trace from hda_controller, same
sequence of action taken:

There's a lot to track here now, but patch #2 seems to work great here!

Patch #6 didn't seem to cause any new problems for me, but the crackling
is still there.

1) Opened VLC with a song
2) Opened discord
3) Started mic testing, output jumped back 5 seconds in the past
4) Ended mic testing, output re synced back.
5) Stopped VLC playing
