Sound problems on Lenovo with Conexant CX8070

RSegvic · 2025-11-29 14:13:00

I'm having sound issues for a longer period of time. Every time it happened, it happened after the first reboot after the update. Sometimes pipewire was down, but that wasn't hard to fix. On the other hand, all sound was still silent. Before, the issue somehow solved itself, by a new update, or by changing to lts kernel, but this time that didn't help, so I decided to ask about it here.

I think that pipewire is working and alsa is detecting the sound card:

[relja@archlinux ~]$ aplay -l

I checked in alsamixer that nothing is muted, and that I can see my card in the gui.

Here is the output of alsa-info.sh:

Should I post this in some other channel maybe?

Get rid of your modprobe.conf trying to set random model values (ideapad technically exists, conexant doesn't, but let's first see what it detects by default). After doing so, run a "sudo mkinitcpio -P" to make sure they are not in the initramfs, install sof-firmware, reboot.

Check your ALSA cards again, do you get some sound now? What output do you get from

sudo fuser -v /dev/snd/*
aplay -lL
speaker-test -Dhw:1 -c2 #Does this give you audible noise?
pactl list cards
pactl list sinks
pactl list sink-inputs

post these in [code][/code] tags.

I moved audio.conf and cx8070.conf from /etc/modprobe.d into backup folder and ran mkinitcpio.
I also installed sof-firmware, although I'm not sure that it applies to my system.
