  Pertaining to 16.04 on a dell XPS 13 9360

  ii  alsa-base 1.0.25+dfsg-0ubuntu5

  Advanced Linux Sound Architecture Driver Version k4.4.0-57-generic.

  
  When headphones are plugged in, there is a clearly audible hiss (white 
noise). This is present as soon as the headphones are plugged in, whether 
'headphones' or 'headset' are selected from the pop-up box. 

  Using alsamixer to debug the issue reveals that it is related to
  "Headphone Mic Boost" - the default setting is: dB gain 0.00, 0.00. If
  this is changed to:

  10.00, 10.00 (one notch up) the hiss disappears. 
  20.00, 20.00 cause a louder hiss and 
  30.00, 30.00 causes an even louder hiss with high frequency audio artifacts. 

  When the headphones are removed and plugged back in the Headphone Mic
  Boost setting returns to dB gain 0 and the problem also returns.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Esokrates]

For the output volume I made the following observations:
* Even with a volume boost of 150% in Pulseaudio (the maximum), the output 
volume is still significantly lower than the unpatched kernel
* With 150% pulseaudio boost, I can hear disortions and crackling, so the sound 
quality gets significantly worse, the over-amplification is too much.

It's a difficult decision as the volume is low compared to before and we
can't really compensate it to the level before the patch.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Esokrates]

Kai, I compile my own kernels and I would like to use this right now,
could you please link me the patch? The test kernel floods my syslog
badly with touchpad debug entries (unrelated to this bug).

Now regarding testing: By software boost you mean we should test both:
Microphone software boost and output volume software boost, right?

Thanks for your detailed answers.

Traditional microphone will lose hardware mic boost.
That said, software boost for mic should good enough.

There's no objective measurement. Use your own ear - if you think the
quality is good, then the quality is good.

Kai, http://people.canonical.com/~khfeng/lp1654448-2/ does not have the
hiss :-).

Would compensating the lower output volume with setting pulseaudio to
100+% make the quality worse? Does setting pulseaudio to e.g. 130%
disort the quality?

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Daniel van Vugt]

I haven't yet tested the latest test kernels but disagree with comment
#85.

As mentioned in comment #77:
"Although I can't help but think that we could still fix this by limiting the 
volume more (or finding some gain setting that is on but shouldn't be). Having 
headphone volume that doesn't go high enough is already a common problem plenty 
of people would be used to. But the important thing is they won't report that 
as a bug, so maybe that's better."

I think we might need more people testing the potential fix to gauge
whether or not a lower max volume is really worse than the hiss.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Esokrates]

Kai, Thank you very much for looking into this and answering questions. Kudos!
I think the behavior should remain as it is if the output volume is reduced 
that much AND support for microphone devices is crippled.
My arguments: It is still better to hear the hiss when music is at low volume 
than have low output volume enforced (on high output volume you do not notice 
the hiss) and additionally lose some functionality.

If you could manage that classic microphones remain operable I would
vote for inclusion.

Yeah but I don't think it gets through to the right people. If I read most of 
the forums discussions no one acknowledges the problem. Only suggestions are to 
install the latest drivers.
The 9360 came out one year after the 9350 and still has the same issue. User's 
experiences are not that grave compared to driver developers that point out an 
issue.

I think they are already aware - a quick google on "xps headphone noise"
shows several results, affecting all OS.

So make the fix in the driver is a more practical approach.

[Daniel van Vugt]

It appears the headphone socket is right on the motherboard:
https://www.ifixit.com/Device/Dell_XPS_13

However, whether it's on the motherboard or a daughterboard probably
would not matter in this case. The problem is so prevalent among XPS 13
models that replacing parts probably would not solve the issue.

IIUC hardware amp (the "Headphone Mic Boost" here) is disabled for
Headphone/Mic/Headset combo jack (which is used on this laptop) on
Windows.

Esokrates,
The reality is that noise happens on a lot of machines - there are already lots 
of noise workaround in ALSA driver - this is just being one of them.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Esokrates]

Kai: Yeah but it would be nevertheless good to communicate that to the right 
people of Dell. 
Is this an integrated component I can't exchange? Is it Intel integrated Audio 
or is it an external chip? 

Hence I would like to do something on hardware level ... is this not
possible?

Daniel expressed what I meant: it's often hard to avoid noise on onboard audio 
chip.
Lots of PCs have background noise - nothing really can be done at software 
level.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Daniel van Vugt]

It sounds like the Windows approach of using a noise suppression filter
might generally be a good idea. It's likely Microsoft has seen many more
laptops and desktops with this same problem.

Although I can't help but think that we could still fix this by limiting
the volume more (or finding some gain setting that is on but shouldn't
be). Having headphone volume that doesn't go high enough is already a
common problem plenty of people would be used to. But the important
thing is they won't report that as a bug, so maybe that's better.

[Esokrates]

Kai: So you are saying the sound card is buggy on a hardware level? Does
this only affect XPS13's or are other Laptops possibly affected too? I
guess all that are using the same soundcard?

How about communicating this to Dell? Or isn't this their fault? Is the
vendor of the sound card to fault? Or is it the headphone jack?

Is a component at fault I could swap on my own?


Daniel: Sry but on all my other laptops even lower end ones this works 
satisfying, this is no excuse for Dell selling me this in a flagship model. 
This is like selling me a crappy Display and telling me for a good Display I 
should use an external one anyway as any Laptop Display is worse than something 
I could connect via HDMI.
Furthermore blocking one USB port of only two is not an option for me ... apart 
from the fact that this is an ultra compact laptop I do not want to attach any 
obstacles to.

Again, if audio quality matters to you, you can also consider a USB DAC
(USB "audio card"). Using the onboard audio socket in any PC is often
prone to system noise.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Kai-Heng Feng]

After discussion with Kailang, he concludes that it's likely to be a
hardware issue - nothing serious can be done in the software level.

If we introduce the workaround, 
- No more static noise in headset
- The headset volume will be drastically decreased, but you can increase the 
maximum volume in PA to 150%.
- The traditional microphone can still be used, but without level 2 and 3 amp.

So it's up to you guys - if you guys think it's a fair trade off, I'll
upstream the fixup. If not, there's nothing more we can do in software
level.

Regarding the second question: The workaround "amixer -c 0 set
'Headphone Mic Boost',0 1" does lower the output volume significantly.
If your patch does the same as the workaround, then the output volume
would be significantly lower, I have not tested this yet though.

I am not a PA expert, but I guess you need to set the sink instead of
source.

I am not sure I fully understand your second question, but output volume

[Esokrates]

Another question: You say your code does the same as the workaround
"amixer -c 0 set 'Headphone Mic Boost',0 1" ... so the output volume is
decreased too with your patch?

does not improve the situation. The hiss remains unchanged for me.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Esokrates]

Thanks very much for the code!! Out of interest, how would you achieve
the noise cancellation with pulseaudio?

I tried

load-module module-echo-cancel source_name=test
set-default-source test

which did not work.

A new device appears called "Built-in Audio Analog Stereo (echo
cancelled with Built-in Audio Analog Stereo)" and one can move sound to
that virtual device. Sound works, but the hiss is still there. I do not
see how it would the hiss ...

Could you elaborate how one would do that with pulseaudio so I can test
it?

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Kai-Heng Feng]

Basically, I did the same thing as "amixer -c 0 set 'Headphone Mic
Boost',0 1", and make the mic pin hidden as well. Otherwise, user space
tools will change the value.

According to Kailang, the "Audio hiss" also happens on Windows - but
windows has Noise Suppression filter, so it's not as noticeable as other
OS.

So there are two ways to workaround the issue - use something like diff
below, or use noise cancellation filter in PA.

When you connect the jack you can choose between 3 options normally
(with the kernel in [1] only two now)... isn't it somehow possible to
operate with microphone disabled by default ... but leave the user the
option to use a traditional mircophone? The white noise should then only
be triggered when the user selects "Microphone"!?

Yes that solves the issue :-). Could you link me the code changes?
But are you sure you can't fix the support for traditional microphones? :-(

Linux kernel in [1] should solve the issue.
However, the jack loses the ability to record via traditional microphone - but 
I think people nowadays use headset most of the time.

[Daniel van Vugt]

At a guess the cause of the problem may be some kind of headphone volume
boost option that's turned on by default, and weirdly turned off by
"'Headphone Mic Boost',0 1". This may not be avoidable interference as
much as just excessive volume boost turned on by default.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Daniel van Vugt]

Unfortunately that did not work.

I can confirm that http://people.canonical.com/~khfeng/lp1654448-artful/
does now remove the 'Headphone Mic Boost' option.

However the headphone audio hiss remains, and now we have no
workaround...

  When headphones are plugged in, there is a clearly audible hiss (white 
noise). This is present as soon as the headphones are plugged in, whether 
'headphones' or 'headset' are selected from the pop-up box. 

  Using alsamixer to debug the issue reveals that it is related to
  "Headphone Mic Boost" - the default setting is: dB gain 0.00, 0.00. If
  this is changed to:

  10.00, 10.00 (one notch up) the hiss disappears. 
  20.00, 20.00 cause a louder hiss and 
  30.00, 30.00 causes an even louder hiss with high frequency audio artifacts. 

  When the headphones are removed and plugged back in the Headphone Mic
  Boost setting returns to dB gain 0 and the problem also returns.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[spike speigel]

/usr/share/pulseaudio/alsa-mixer/paths/analog-input-headphone-mic.conf

I just found this from a separate bug thread.  This looks interesting.
The options for volume are:

volume = ignore | merge | off | zero | 

# What to do with this volume: ignore it, merge it into the device
# volume slider, always set it to the lowest value possible, or always
# set it to 0 dB (for whatever that means), or always set it to
#  (this only makes sense in path configurations where
# the exact hardware and driver are known beforehand).

Is this touched by Pulse when updates are applied?  I was going to test
out zero and ignore to see what happens.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[spike speigel]

I still haven't figured out how Pulse determines the default levels it
forces upon the user at each start of the service.  I think it should
respect those levels set within ALSA/the system.  If Pulse can't respect
selected values, then I'd like to know where it gets its default values.
That way I can manually change them and force my default values down
Pulse's throat.

pactl is a hot mess to understand.  I don't see a way to set volume on
ports at all.  Maybe it isn't even possible using pactl.

/etc/pulse/default.pa
/etc/pulse/system.pa

don't seem to provide help either.  I tried modifying a few things
there, and it broke the automatic muting when switching between
headphones and internal speakers.  So I put all that back the way it
was.

I also noticed if:

1.  I have alsamixer open along with pavucontrol
2.  Set the headphone mic dB gain to 10% in alsamixer
3.  In pavucontrol select the "Microphone" from the dropdown under the "Input 
Devices" tab

Result:
pavucontrol resets the dB gain to 0%, "the default" without me even touching 
the volume slider...in fact I CAN'T touch the volume slider for the mic.  Why 
can't Pulse work with functionality ALSA clearly provides?

Googling for answers on pulse and volume issues just seems to return a
lot of annoyed users and scripted hack answers which really aren't
solutions.

If I had a way to set the port volume for the mic and have it remain
that way permanently, that would work for me.  After reducing the dB
gain I can still up the volume to compensate without the hiss returning.

If we can determine it is a bug somewhere and fix it at the root, even
better.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Esokrates]

I tried blacklisting the snd_hda_codec_realtek module, sound works, but
now I can hear the coil whine, depending on the activity of the cpu/gpu.
Moving the mouse pointer around is clearly audible etc.

[Touch-packages] [Bug 1654448] Re: XPS 13 9360 and 9350, Realtek ALC3246, Headphone audio hiss

[Daniel van Vugt]

Well, the problem might be more noticeable with low-impedance
earphones/headphones. So more likely earphones, but possibly also
headphones. (<--- This is now guessing)

Yes I would agree (and mentioned in comment #37) that the workaround
makes audio quieter. That might be the best solution possible, but
hopefully not.

One problem is that headphone sockets are notoriously noisy in many
computers. And it's often not a problem that can be fixed in software.
My general recommended solution on any PC is a hardware one: Always use
a USB DAC (digital-to-analog converter), AKA a "USB sound card". That
separates the analog audio signal generation from the physical machine
and avoids such noise/hiss problems.

@vanvugt: I can clearly reproduce the problem with headphones too, I do
not notice they "hide" anything.

I noticed the hiss listening to music so I can always clearly hear it
and it becomes very apparent in a quiet environment.

On another note, with the workaround in place the audio is way to quite, 
vanvugt, would you agree?
Setting down the volume generally should not be a solution to this bug 
(compared to the volume of other phones/laptops).

[Daniel van Vugt]

@kaihengfeng: I found the problem was only really noticeable with
earbuds. Headphones tended to hide the problem.

Although it's also worth noting the workaround 'amixer -c 0 set
'Headphone Mic Boost',0 1' sounds like it's working because it actually
reduces the audio output volume/gain. With the workaround enabled, ALL
audio is quieter so (like using big headphones) the problem could become
unnoticeable just because of that. So saying the problem and the
solution are directly related to 'Headphone Mic Boost' might be a red
herring.

[Daniel van Vugt]

^^^
Confirmed on an XPS 13 9350 too. And the 'Headphone Mic Boost' workaround 
works. Although like others, I find that concerning since it should in theory 
make the problem worse or make no difference.

Also confirmed the problem persists with:
 * 3-contact earphones (Sony)
 * 4-contact Apple Earpods
 * 4-contact Bose AE2 headphones (Apple-compatible cable)

All of these experience the hiss, but the Bose almost none (much harder
to notice). I think the most interesting test should be to try some
proper Android/Samsung/Nokia wired headphones/earphones  in future.

If it turns out there's nothing wrong with the physical connection then
this sounds like a kernel problem still.

kaihengfeng: I have just tested your kernel on zesty and it made no
difference. The problem remains and the same old amixer workaround is
required.

Bug description:
  Pertaining to 16.04 on a dell XPS 13 9360

  ii  alsa-base 1.0.25+dfsg-0ubuntu5

  Advanced Linux Sound Architecture Driver Version k4.4.0-57-generic.

  
  When headphones are plugged in, there is a clearly audible hiss (white 
noise). This is present as soon as the headphones are plugged in, whether 
'headphones' or 'headset' are selected from the pop-up box. 

  Using alsamixer to debug the issue reveals that it is related to
  "Headphone Mic Boost" - the default setting is: dB gain 0.00, 0.00. If
  this is changed to:

  10.00, 10.00 (one notch up) the hiss disappears. 
  20.00, 20.00 cause a louder hiss and 
  30.00, 30.00 causes an even louder hiss with high frequency audio artifacts. 

  When the headphones are removed and plugged back in the Headphone Mic
  Boost setting returns to dB gain 0 and the problem also returns.
