No sound in xfce4 on chromebook using crouton

I am running xfce4 on a chromebook using crouton . It is xfce4 version 4.12 distributed by Xubuntu.
The sound works fine on chrome OS but when switched to xfce4 suddenly it does not work . Previously it had worked properly for years.
Pulse audio shows one output device cras and it isnt muted .
The chromebook is a acer chromebook 15.

I tried removing and reinstalling pulse audio but no change.
I'm not sure what else to do , any help would be greatly appreciated

Re: No sound in xfce4 on chromebook using crouton

Hi 25morefloors, and welcome to the forum.

Chromebooks often need a tweak or two to get sound working. Run this in the terminal and paste back the output it returns:

aplay -l

Hopefully that will give enough info to know what fix to apply.

Also, the newest kernels are adding more support. It's possible a 5.3x kernel might simply work.

Darn. That one doesn't help. I need a codec to be able to find the right fix. Let's see if either of these get's us there:

dmesg | grep -C1 -E 'ALSA|HDA|HDMI|snd[_-]|sound|hda.codec|hda.intel'
journalctl -k | grep -Ei "snd|sound|audio|multi"

Re: No sound in xfce4 on chromebook using crouton

Something you've done has applied a firmware patch:

[    5.744041] hda-intel 0000:00:1b.0: Applying patch firmware 'auron_yuna_alsa.fw

Assuming you're not trying to get audio over HDMI, that patch is obviously not working for you. Any idea what you did to install that? Looks like it's a chromiumos thing. See if commenting out the single line in /etc/modprobe.d/alsa-auron_yuna.conf (or similar name) then running

sudo alsa force reload

allows the earlier commands to show the codec in use.

Re: No sound in xfce4 on chromebook using crouton

Did a little digging. I don't understand chroot stuff, but if you'd been running Xubuntu natively, I'd be instructing you to edit, as root, /etc/modprobe.d/alsa-base.conf adding this new line at the bottom:

options snd-hda-intel model=alc283-dac-wcaps

Then save the file and reboot.

That is basically all that firmware patch is doing, but may be doing in a way that isn't proper, I can't say.

Sources:
crouton = https://github.com/dnschneid/crouton
firmware patch = https://chromium-review.googlesource.co … na_alsa.fw

I hope that's of some help.

Re: No sound in xfce4 on chromebook using crouton

It seems that neither alsa-auron_yuna.conf nor alsa-base.conf are files in /etc/modprobe.d

these are the files that are there

blacklist-ath_pci.conf   blacklist-framebuffer.conf   blacklist-watchdog.conf  fbdev-blacklist.conf  mlx4.conf
blacklist-firewire.conf  blacklist-rare-network.conf  blacklist.conf           iwlwifi.conf

Do you think that is the problem ?

I just want to thank you again for your continued support.

Re: No sound in xfce4 on chromebook using crouton

Yes, that could very well be the problem. I could be wrong with my lack of knowledge about crouton.

I have 21 files in that folder, from a standard install of Mint 18.3, including the 9 you have. I'm sure some of them are not relevant to your issue, but I'd think the lack of alsa-base.conf might be what's preventing you from getting sound.

Assuming you use this like a normal install of Xubuntu, I believe this might be what you need to run in the terminal

sudo apt-get install --reinstall alsa-base

Hope that helps.
