After an upgrade to 22.04 my speakers no longer function properly. With the volume at 153% in pavucontrol I can barely hear it (need to put my ear almost next to the speaker). I remember I had the same issue after a fresh install of 21.04 back in December, but I can no longer recall how I fixed it.

alsamixer has Speaker and Bass Speaker at 00 and those cannot be adjusted, see screenshot. DAC1 and DAC2 control left and right speaker respectively (when at 0 can not hear anything even with my ear at the speaker).
