ALSA: no sound card Linux/x86 5.10.136

patriot1919 · 09-20-2022, 07:23 PM

Hello,

Im having trouble getting sound from any source. Under settings only option is dummy sound, which when a video is playing for example, you can see the sound bar moving, but no sound is actually coming from the speakers, headphones, ect. I have tried many typical solutions, but the issue is ALSA is not recognizing the sound card.

just to be clear ive tried alsamixer, pulse audio control, pauv. ect and nothing works because no card is shown.

any help would be appreciated, im new to this, so please be specific with any advise. thanks

Welcome 2LQ!!! I hope someone who knows about audio=sound will come along to help (BOTH of us)!!!

I have never heard of a Google Coral laptop!!! (Mine: old 2006 Toshiba M115-S1061 MX-21_386)

There have been a couple of recent threads about the dummy audio device creating a problem:
https://www.linuxquestions.org/quest...io-4175716724/
https://www.linuxquestions.org/quest...nd-4175716850/
(Maybe tell us more about your web searching on this)

Big kudos for posting all that information in code tags! Best wishes! Bye.

I wonder if the Linux Sound Programming book ISBN 1484224957 would help (? I'll check z-lib)

My info: http://termbin.com/lrbf from https://gitlab.freedesktop.org/pulse.../utils/pa-info (I'd also suggest this web search: Linux audio Diagnostic script )
http://termbin.com/xymi

** Initially, there was only the option of the headphones and no audio was coming out of the headphones. Somewhere I saw something about uncommenting something in /etc/pulse/default.pa
I think (but not sure) uncommenting the one recommended line did nothing, so I uncommented like a dozen things. Then more reasonable devices appeared, but still no sound. Then I collected the above info. Yes, sorry, I am clueless here!!!

root:~# aplay -l

#1 make sure /proc /dev/shm /sys are all mounted and try again if they were not

#2 probably systemd didn't create /dev/sndFOO device files, once they are created aplay -l will show the card and alsamixer aplay will work immediately from where you sit

i have a script i did not post that does that which doesn't depend on systemd

all you need to know is under /sys
