[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dawid]

I've fixed this issue on my Asus UX550VE, Ubuntu 20.04, kernel 5.4.0-42.
I followed Optiman's instructions, which are supposed to "activate
bottom speakers" using jack retasking:

or-muted-no-middle-ground

  ALC295 codec seems to have Master and PCM channels swapped

Bug description:
  When trying to use pulseaudio to control volume on my ASUS Zenbook Pro
  UX550VE *uses AC295 audio codec) I noticed that pulseuadio is varying
  the Master ALSA channel. If I vary that channel in alsamixer I get no
  variation in volume. If I vary the PCM channel instead I get the
  desired effect that volume buttons should have. Since pulseaudio
  varies the Master channel by default and does not respect any
  configuration settings telling it to use other settings, I suggest
  swapping these two channels so that pulseaudio works out of the box.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Mario Vukelic]

Still occurs on this Asus in 20.04 with kernel 5.4.0-15 and the
-proposed -17.

Super annoying, I have to fix this for the Asus' owner by adding the
[Element Master] workaround on every Ubuntu upgrade or in case the
responsible package updates.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Mario Vukelic]

Still occurs on 19.10 after upgrade, on the same Asus ZenBook Flip 15 UX561UD 
as in comment #30. 
As the upgrade replaced 
"/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common", had to 
reapply the workaround from comment #8 (which is kind of bearable on a machine 
that is has a proper admin, but sucks for normal people)

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

Your patch added an extra requirement to get sound, i.e. that the
Headphone volume has to be raised in order to get sound from speakers.
It is not only counter-intuitive but also works against how PA operates
in general. PA does not raise Headphone volume unless headphones are
actually plugged in.

  Confirmed

Bug description:
  When trying to use pulseaudio to control volume on my ASUS Zenbook Pro
  UX550VE *uses AC295 audio codec) I noticed that pulseuadio is varying
  the Master ALSA channel. If I vary that channel in alsamixer I get no
  variation in volume. If I vary the PCM channel instead I get the
  desired effect that volume buttons should have. Since pulseaudio
  varies the Master channel by default and does not respect any

  swapping these two channels so that pulseaudio works out of the box.

Master should also change the speaker volume with my patch. But probably
we should keep it the way it is...

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

When using a stock kernel and stock PA/Alsa configurations, the volume
controls end up raising Master only without also raising PCM as PA
thinks that PCM and Master are merged. This codec does not require
raising Headphone volume for speakers, it only requires it when actually
using headphones. The headphone scenario works perfectly out of the box.
Please do not change anything with headphones as that would be a
regression.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Kai-Heng Feng]

That's right, what you describe is exactly what we are looking for: to
use headphone change speaker volume.

I am not sure why default PA doesn't work though. Do you mean that after
removing all PA and ALSA conf, the volume slider in gnome-control-center
does not work?

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

I think Bass Speaker,Master and Headphone all have amp-out capability.
They need PCM to be raised. PCM is analogous to a mixing console channel
fader, and the former three are analogous to volume knobs on audio
amplifiers.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

No, using stock pulseuadio configuration or the one I had patched will
not work. I had to increase the headphone volume with alsamixer
manually. Before your patch, I could change the volume by keeping master
at 100% and vary the PCM channel. Thr PCM channel seems to alter the
amplifier attached to the main speakers. The amplifier attached to the
subwoofer has a separate channel named bass speaker in alsamixer. My
pulseuadio config patch with a stock kernel allows changing volume from
the GUI and hotkeys without any fuss.

That’s the idea. Because the default speaker does not have amp-out
ability, reroute it to use headphone’s amp-out to make its volume
changeable.

I think you can change the speaker volume via default GUI widget now
without changing any config file, right?

Title:
  ALC295 codec seems to have Master and PCM channels swapped

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When trying to use pulseaudio to control volume on my ASUS Zenbook Pro
  UX550VE *uses AC295 audio codec) I noticed that pulseuadio is varying
  the Master ALSA channel. If I vary that channel in alsamixer I get no
  variation in volume. If I vary the PCM channel instead I get the
  desired effect that volume buttons should have. Since pulseaudio
  varies the Master channel by default and does not respect any
  configuration settings telling it to use other settings, I suggest
  swapping these two channels so that pulseaudio works out of the box.

[Dylan Borg]

The provided kernel requires all three of Headphone,Master and PCM to be
raised for sound to come put of the speakers. The stock kernel needs
only Master and PCM to be raised.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

The provided kernel has swapped the speaker and headphone channels. The
Headphone channel in alsamixer is controlling the laptop speakers! If
you need some alsa dumps to aid in correctly mapping the channels do not
hesitate to ask.

Is it based on a kernel that is 4.13.5 or higher? 4.13 till 4.13.4 lead

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

I cannot do that, the current nvidia drivers do not build against 4.14.
If possible I could try a patches 4.13.9 kernel instead.

I wish anyone luck when trying to improve the status of the driver for
this codec. Some aspects do feel weird such as the interplay between
mixer channels.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

I got a better result by changing "volume=ignore" to "volume=100", that
makes ure teh Master channel is stuck to 100% so teh woofers get used.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Kai-Heng Feng]

It's actually a valid bug. The problem is that node 0x06 does not have
amp-out capability. Also there's no mixer that can connect 0x06 to
another node with amp-out capability.

I'll ask ALSA expert how to solve problem like this.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Dylan Borg]

Ok, this issue can be fixed by modified pulseaudio instead of the
kernel. Will mark this as fixed. For anyone else coming across this
having the same issue please add:

[Element Master]
switch = mute
volume = ignore

before the PCM settings block in "/usr/share/pulseaudio/alsa-mixer/paths
/analog-output.conf.common"

** Changed in: linux (Ubuntu)
   Status: Incomplete => Invalid

  ALC295 codec seems to have Master and PCM channels swapped

Status in linux package in Ubuntu:
  Invalid

Bug description:
  When trying to use pulseaudio to control volume on my ASUS Zenbook Pro
  UX550VE *uses AC295 audio codec) I noticed that pulseuadio is varying
  the Master ALSA channel. If I vary that channel in alsamixer I get no
  variation in volume. If I vary the PCM channel instead I get the
  desired effect that volume buttons should have. Since pulseaudio
  varies the Master channel by default and does not respect any
  configuration settings telling it to use other settings, I suggest
  swapping these two channels so that pulseaudio works out of the box.

[Dylan Borg]

The DKMS isues should be fixable by disabling "AMD Secure Memory
Encryption" i.e. SME support in the 4.14 kernel.

NO, this is a fresh install on brand new hardware. Also I need the
nvidia driver to work on thsi system which is impossible for now with
the the 4.14 kernel.

[Kernel-packages] [Bug 1721345] Re: ALC295 codec seems to have Master and PCM channels swapped

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  ALC295 codec seems to have Master and PCM channels swapped

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When trying to use pulseaudio to control volume on my ASUS Zenbook Pro
  UX550VE *uses AC295 audio codec) I noticed that pulseuadio is varying
  the Master ALSA channel. If I vary that channel in alsamixer I get no
  variation in volume. If I vary the PCM channel instead I get the
  desired effect that volume buttons should have. Since pulseaudio
  varies the Master channel by default and does not respect any
  configuration settings telling it to use other settings, I suggest
  swapping these two channels so that pulseaudio works out of the box.
