Sound detected by pavucontrol but no actual sound

Hello,

I just installed Arch, and I hope this is the right place for my question.

I was trying to set up my audio with the https://wiki.archlinux.org/title/Advanc … chitecture page, and when I arrived at the `speaker-test` part, I got the following error:

ALSA lib pcm_dmix.c:1000:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

I used alsamixer to unmute all my outputs, and when I play a video, pavucontrol's bar is moving, telling me that the audio is playing. However, I don't hear anything...

I get a similar error with dmesg:

[   23.872592] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_dai_hw_params on iDisp1 Pin: -22

I tried reinstalling the alsa packages and restarting the services, but nothing seems to make my audio work

Any idea where I could look?

Fyi, I have those audio cards

$ lspci | grep -i audio   
0000:00:1f.3 Multimedia audio controller: Intel Corporation Raptor Lake-P/U/H cAVS (rev 01)
0000:01:00.1 Audio device: NVIDIA Corporation AD107 High Definition Audio Controller (rev a1)

Thank you for your time

EDIT : Once every while, when I kill pulseaudio with

$ ps -ax | grep audio | grep -v grep | awk '{print $1}' | xargs kill  

the audio starts works, but then 5 minutes later it doesn't work anymore...
