Hi, I have a fresh install on a Lenovo T14. It has integrated Intel sound hardware. Everything works except I cannot get any sound.
I've tried the following:
- Added myself to group "audio"
- Used alsamixer to make sure sound is unmuted
- Installed pulseaudio
- Added a line in modprobe.conf to blacklist snd-intel8x0m as some have suggested (see upload link below)
When I use aplay to play an xxx.wav file, it seems to work fine... I can see the amplitude display jumping around as the file plays.
Looking at /dev/snd it seems like there should be other devices ? (See link below)
Here is some info I've collected:
Output from alsa-info.sh http://ix.io/2v9x
Listing of /dev/snd: http://ix.io/2v9z
Example of things I tried in modprobe.conf http://ix.io/2v9y
============================================================
I finally found the solution to this, as posted by another user (link below).
Add this line to /etc/default/grub to disable the snd_hda_intel.dmic_detct feature:
GRUB_CMDLINE_LINUX_DEFAULT="snd_hda_intel.dmic_detect=0"
Then run grub-mkconfig to regenerate the grub.cfg file, and reboot.

I have a T14 Gen2 Intel work laptop and while the solution above worked as a workaround for having some sound, but the laptop internal microphone did not work. (If I connected a headset with microphone to the jack, it worked fully, also its microphone).

After some searching around, I found the solution here: https://forum.manjaro.org/t/howto-prope … udio/93628
So basically you need to undo this workaround, reboot (not sure if needed), install the sof-firmware package, reboot, and everything should work after that. Everything works for me now, including the internal mic.
Just for the record, I am using the current version, so 2.2.4-1 of the sof-firmware package.
