Created attachment 1074539 [details] 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 retrieved while doing the test
I don't know if I shouldn't open another bug but flat-volumes have a serious bug , I explained first here https://bugs.kde.org/show_bug.cgi?id=355758 but now I see that same happens in pavucontrol , in KDE, even without kmix running. Increasing the volume of one stream increases the volume of master channel , doesn't make sense I increasing volume sound in one stream audio and master audio is also increased ? . When I choose volume in one stream , master volume control shouldn't change to the same level of sound of the stream. Worst is I have a app saved which the stream was saved at maximum, I left application , I reduce master volume to very low level but not mute, I open the app and volume goes to maximum (same level of the stream of the app). Disabling flat-volumes , things back to normal i. e. master volume doesn't change when I change the level of a stream sound .

You posted in the wrong bugreport, you should leave a comment in https://bugzilla.redhat.com/show_bug.cgi?id=1265267
I don't want disable flat-volumes, I want someone fix flat-volumes in pulseaudio
(In reply to Sergio Monteiro Basto from comment #3) > I don't want disable flat-volumes, I want someone fix flat-volumes in > pulseaudio Then open a pertinent bugreport
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
I'd encourage this to get filed upstream @ https://bugs.freedesktop.org/enter_bug.cgi?product=PulseAudio
OH, it already is, then there's probably little point in keeping this one.
