[Linux Mint 20.1 MATE] Sound card not detected / Dummy Output

Post by Loxoq »

Hello everyone, I'm making this post because I'm kind of desperate to find a viable solution to my problem.

To elaborate what I'm saying in the subject : I have Linux Mint 20.1 running on an Acer Swift 3 SF314-57, dual-booted with windows 10.
Fast Boot & secure boot are of course disabled. My sound card is sometimes (it is rather random, or it may look as if) not recognized by the system (

Code: Select all

aplay -l
is telling me that no sound card has been found), and I have, for only option in pavucontrol, a Dummy Output.

My main problem here is that each time I shutdown or reboot my laptop when a Dummy Output is shown, the laptop freeze on the LM logo (no keyboard input is possible moreover), resulting sometimes in the break of my boot process (I need to reinstall grub from a live session each time it happened, it's annoying ngl).

I have explored many leads that I found online :
  • changing the kernel --> Nothing really changed (from 5.4 to 5.10), the bluetooth became more stable though.
  • Reinstalling alsa, same, nothing changed
  • Checking if Timidity was the cause of my problem, turns out it wasn't
I'm rather confused about this whole stuff, I suspect one or several processes may disturb the well-functionnement of the sound (maybe at shutdown when the sound is well working, or at Linux' start, I don't know), but I'd like to hear your opinion about it, beacuse I have a limited knowledge of Linux atm.

A few commands output that may be useful (note that these have been taken while my sound was not working) :

I'm bumping this thread because I encountered a similar problem. I installed Timidity and my sound is gone.
