Debian Testing doesn't detect soundcard

Postby speltriao1 » 2020-09-07 14:26

Hello, I'm trying to get Debian to recognize my intel's laptop speakers and internal microphone.

On arch, I had to install sof-firmware, The Free Open Sound Firmware, to get them working.

I can't find this package on Debian, I've installed linux-firmware, firmware-intel-sound, alsa*, pulseaudio* etc. But with no success.

Someone knows how to install sof-firmware on Debian?

Thanks!

How do you know it's not detected? It may simply be turned off. Check alsamixer and/or pavucontrol.

Debian haven't packaged the firmware yet so just follow the steps in the Arch PKGBUILD to either install it manually or package it up for Debian yourself.

SOF may be a red herring. Intel audio usually "just works". I suspect, as Bulkley said, it's just not turned up.
Check alsamixer and pavucontrol as suggested.
Also to see if device is recognised, post here the output of:
Code: Select all
lspci -k |grep -i -A 3 audio

and
Code: Select all
aplay -l

Code: Select all
lspci -k |grep -i -A 3 audio

Code: Select all
aplay -l

OK. I think Head_on_a_Stick's answer above is your best bet. Install firmware manually or build a Debian package.

I think I can compile it, but I have a doubt: With every Kernel update, will I have to compile it again?

No. It's firmware, not a driver. It usually won't care what kernel is active whereas drivers are specific to a kernel.

OK, I see. Probably it's going to be enough for solving my case.

I don't think I have the knowledge to package this as a .deb file.
How can I suggest Debian maintainers to package this up?

I think it's an important, FOSS and useful package, specially for newer hardware and for new users coming to Debian.
