[BUG] ASUS ROG Zephyrus M16 GU603ZX volume/bass control issue

[dhalucario]

Describe the bug
Audio device(s) do not seem to work properly. Trying to change the volume either seems to fade between bass speaker and normal speaker or only changes the volume of the normal speaker.

I have been sent here by the PipeWire team to forward this issue to you.

To Reproduce

• Install Fedora or Arch, I am using Arch for this example.
• Open alsamixer, press F6 to switch to HDA Intel PCH.
• Master only seems to change volume for the normal speakers.
• Speaker causes audio to cross fade between speaker and subwoofer
• PCM causes volume to go up for speakers and subwoofer.

Reproduction Rate
Consistent. Happens every time seemingly.

Expected behavior
I would expect there to be a working slider for Speaker, Bass Speaker and Master volume.

Impact
This is a showstopper for me when I try to use the speakers at all and an annoyance when I use the laptop with headphones.

try this first @dhalucario, it's likely to be a codec issue, not an SOF one. SOF provides a 2 channel stream. the subwoofer is handled by the HDaudio codec.

Hey, I added the line to the config, rebuilt dracut and restarted the computer. The same issues occur and I can't see any changes.

Thanks for testing @dhalucario, so it's not an SOF issue but an HDaudio codec management issue. copying @tiwai in case there's a known issue on this ALC285-based platform.

I can confirm that the same problem occurs on the ALC285 on ASUS ROG Zephyrus G16 GU6003VV. On alsamixier, my bass speakers have a value of 00 and I cannot increase/decrease it; sound is full of treble, but no bass output.

Any updates on a potential solution @tiwai, @plbossart, or @dhalucario?

If not, any suggestions on how to deal with the HDaudio codec management?

Thanks.
