Baytrail sound appears functional, yet no sound.

This is a chromebook that was functioning fine a few days ago, however I was forced to reinstall, and ever since then, I cannot get audio... and not for a lack of trying. To be fair though, ALSA/pulseaudio is quite foreign to me because it has always just worked.

I am currently on the latest linux 5.2.13 kernel, but I have also tried JSkier21's kernel (with UCM files) as well as some LTS kernels, and they all provide the same outcome. My sound card is visible and when I play audio from anything, I can see the activity in pavucontrol, but I have no sound. I know the sound works with the latest kernel that I am currently on from the previous install, so I'm sure it's just something that I am clueless about and apparently I just got lucky last time around.

Here is the relevant info:

pacmd list-cards

I have also unmuted the required sections with alsamixer as well. There's no Master though. That last output from pulseaudio.service is obviously a little concerning, but I'm just not sure if it's relevant. Searches say that it's a deal breaking compatibility issue, but I've had pulseaudio working on this machine in the past.

Thanks for your time. Happy to provide anymore info as needed.

Re: Baytrail sound appears functional, yet no sound.

Hi,

Audio issues are very common in a chromebook. My chromebook currently has audio with the LTS kernel, although my board is a Swanky.
The outputs from pacmd and aplay are almost identical, and I'm using the same kernel module as you.
I do not see the error in the systemctl output.

I'm not sure I can help you with the issue, but lets try some things:

Could you provide the output of amixer?

Also, in alsamixer if you haven't tried this yet, press F6 to choose a sound card, and choose the chtmax98090. There are close to 100 entries in this card, you can scroll with your arrow keys. Make sure these are unmuted:
Speaker, Speaker Left, Speaker Left Mixer, Speaker Right, Speaker Right Mixer. And waaaay over to the right: Left Speaker Mixer Left DAC, and Right Speaker Mixer Right DAC.

Last, in Pavucontrol, make sure that the "Built in audio" that is selected is the one corresponding to the cht card, not the intel one (that's for HDMI audio).

I hope this helps. Good luck!

Re: Baytrail sound appears functional, yet no sound.

Yeah, I remember it being a struggle the last time around, but it's really giving me problems this time.

Here's the amixer output

Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 65536 [100%] [on]
  Front Right: Playback 65536 [100%] [on]
Simple mixer control 'Capture',0
  Capabilities: cvolume cswitch cswitch-joined
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 65536
  Front Left: Capture 65536 [100%] [on]
  Front Right: Capture 65536 [100%] [on]

Alsamixer is all correctly set up and was done so using the UCM files from here - https://github.com/plbossart/UCM

Pavucontrol is also set up to play on built in speakers. It's really a mystery to me as to why it doesn't work this time around.

Re: Baytrail sound appears functional, yet no sound.

That's the pulse compat mixer, post

amixer -c1

instead.
