Sound not working in Arch Linux

[brunocmorais]

Hello there! I generated an image of Arch Linux using Breath and everything worked flawlessly except for the audio. I tried the same steps contained in the sof-setup-audio script, but no success. Using a generated Ubuntu image with the same kernel as Arch (5.10.88), audio works normally. I tried using the more recent 5.10.102-dirty kernel, but it didn't work too. I installed all the alsa related packages and sof-firmware. My laptop is a Samsung Chromebook 4 (Bluebird, Octopus).

Here's the output of # dmesg | grep sof in Arch: dmesg.txt

In comparison, the output of same dmesg in Ubuntu: dmesg_ubuntu.txt

Thanks in advance, if I can provide any further information or help, please let me know!

What does speaker-test output? Maybe running pulseaudio -k would work?

[brunocmorais]

@MilkyDeveloper speaker-test complains about not having any sound card available. I tried running pulseaudio -k and it runs without errors, but no sound. I ran alsa-info and it shows the sound card as available, but not recognized by alsa.

Try running sudo alsa-info, but when it asks for the link/uploading it online, say yes and share the link here.

[brunocmorais]

The alsa-info script from Arch doesn't have the upload feature like Ubuntu, so I'm attaching its output here.

alsa-info.txt

This is the alsa-info generated inside Ubuntu.

This is because snd_hda_intel isn’t being blacklisted. Will fix this soon.

@brunocmorais is the issue still persist ? Please, create another breath usb and test if it is working now. You can follow the doc
