Debian 12 32bit: big noise in loudspeaker

**maketopsite** · August 27th, 2024

Happens after sound initialization during boot. Persists until closing DE during reboot.

It resembles as if there is no signal to loudspeaker and you turn volume to max.

Values in pavucontrol and alsamixer are as usual - in the "middle". Other sound play normally.

Code:

echo 0 > /sys/module/snd_hda_intel/parameters/power_save

did not help.
