pulseaudio logs
Description of problem:
Let's assume that master audio volume level is at 50%.
Let's assume that Amarok player audio volume level is at 50%, so at the same
level of master audio volume.
In this situation if you change the master audio volume level, Amarok player
audio volume level will change too, at the same percentage. No problem till
here.
Now you set a certain offset between Amarok volume level and master audio
volume level, for example by decreasing Amarok by a 20%. Then try to change the
master audio volume level, increasing or decreasing it quickly. You will ear
audio crackling.
Disabling flat-volumes in /etc/pulse/daemon.conf solves the problem
Version-Release number of selected component (if applicable):
pulseaudio-6.0-8.fc22.x86_64
I attach output of
$ pulseaudio -vvv
