How do I change the way Ubuntu adjusts my volume mixer levels?
Pulseaudio's default volume slider doesn't work well with my audio card: when I change the volume (through the volume icon or the keys on my keyboard), for the first 50% the PCM volumes gets adjusted and for the next 50% the master one.
This change happens in big increments of ~20%. The changes to PCM barely affects the volume level, while the Master slides does.
This makes the volume slider rather unusable: it's either way too low, or too loud and I can't set it properly.
Is there a way, preferably through pulseaudio and not by rebinding my keys to use amixer (as suggested in another post here) to only change the master volume without ever touching PCM?
I know you can play around with the
/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common file to achieve that effect, but this does not seem to be the proper way to change this: the change will get reverted next time pulseaudio gets updated.
