There is a fix for this issue. commit d2cd795c4ece1a24fda170c35eeb4f17d9826cbb Author: Jaroslav Kysela <pe...@perex.cz> Date: Fri Nov 29 15:40:27 2019 +0100
ALSA: hda - fixup for the bass speaker on Lenovo Carbon X1 7th gen The auto-parser assigns the bass speaker to DAC3 (NID 0x06) which is without the volume control. I do not see a reason to use DAC2, because the shared output to all speakers produces the sufficient and well balanced sound. The stereo support is enough for this purpose (laptop).

I can only toggle sound on (= 100%) and off (= 0%). What I found out is that the Master channel seems to have no effect for volume adjustments, but the PCM channel does. If the sound is muted, PCM is set to 0 and therefore the sound is toggled off, but when I increase the sound a bit, PCM jumps straight to 100, causing the speakers to be very load. I have attached alsa-info output.
