Occasionally, I can increase kmix's volume to its maximum (using the volume hotkeys), but the sound is still very quiet. I can open up
alsamixer, and see
Master at ~8%, even though kmix's volume is 100%. If I change kmix's volume, I can see similar changes in
Master, but only up to ~8% maximum.
I can manually increase
Master. This fixes the problem for a reasonable amount of time; changing kmix's volume results in similar changes in
Master up to its maximum. However this fix seems to revert in a seemingly random and non-reproducible way (perhaps after a restart?).
Is there a way to ensure that setting kmix to maximum results in
alsamixer at maximum?
I'm not sure if it's related, but when I change the volume in kmix,
PCM varies seemingly randomly from 100 to 98 and 99, and
Headphone goes from 0 (at 0% kmix) to 55 (at 5% kmix) to 100 (≥10% kmix). As stated above,
Master increases with changes in kmix.
