No sound on fresh chromebook install

I am unable to get any sound out of my speakers or headphone jack on my Toshiba Chromebook 2. I've tried several configurations with no luck. I have tried reinstalling alsa-lib and alsa-utils along with the config files and started from scratch. I currently have pulse completely removed. This is my current state:

 /etc/modprobe.d/alsa.conf

options snd slots=snd_hda_intel
options snd_hda_intel index=0
/var/lib/alsa/asound.state 
pcm.default {
	type hw
	card 0
}
ctl.default {
	type hw
	card 0
}

When I change asound.state it seems to restore itself to the above version. I really do not have much of a clue what I'm doing here, any advice much appreciated.

Re: No sound on fresh chromebook install

Have you unmuted the channels? Use alsamixer to see if they have been unmuted or not.

I tried doing this with amixer (also having issues with my F key config so I've avoided alsamixer). It would seem I don't have a 'Master' channel, is this an issue?

 sudo amixer -c 0 set IEC958 playback 100% unmute
Simple mixer control 'IEC958',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]
 sudo amixer
Simple mixer control 'IEC958',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]
Simple mixer control 'IEC958',1
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]

Re: No sound on fresh chromebook install

It seems that only your HDMI port is getting recognized, not the audio jack.

Re: No sound on fresh chromebook install

Hi,

same problem here. I have LTS kernel, so I've installed linux-lts-max98090-4.9.26-1-x86_64.pkg and linux-lts-max98090-headers-4.9.26-1-x86_64.pkg and changed the asound.state file, but with no luck.

Any help is very appreciated.

Re: No sound on fresh chromebook install

@Stormy, do you have the same Chromebook model? Have you tried using some other (live) distro?

Re: No sound on fresh chromebook install

More importantly is it really the same problem? That is, no analog but only HDMI device listed in aplay --l?

P.S. why should one look into mixer controls and asound.state in that case?

Re: No sound on fresh chromebook install

Yes, same model: Toshiba Chromebook 2.

Tested with Ubuntu Xenial, and Antergos live distros, before trying Arch.

And yes, only HDMI listed in aplay --l
