Just installed Elementary OS 6.1 on my HP x2 Detachable 10-p0XX, everything was working just fine (sound too). After updating all apps from app center and rebooting device, sound got lost. I can see my audio device in alsamixer, it is unmuted, I can control volume using both tray icon and alsamixer, but the speakers don't make a sound.

cat /proc/asound/cards gives mi following:

 0 [Audio          ]: HdmiLpeAudio - Intel HDMI/DP LPE Audio
                      Intel HDMI/DP LPE Audio
 1 [rt5640         ]: SOF - sof-bytcht rt5640
                      HP-HPx2Detachable10_p0XX--827C

I've tried reinstalling pulseaudio, setting rt5640 as default by creating /etc/asound.conf. Nothing changed.

Is there a way to fix it without reinstalling system?

Alsamixer

built-in mixer

Got it by unmuting DAC MIXL, DAc MIXR, SPOR MIX DAC R1, SPOR MIX DAC L1 for my speakers, and all HP and HPO with Stereo DAC MIXR DAC L1&R1 for my headset using alsamixer.
