             Bug #: 48284
           Summary: Underlying h/w volumes are still adjusted due to flat
                    volume logic even when the stream is muted.
    Classification: Unclassified
           Product: PulseAudio
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: core
        AssignedTo: pulseaudio-bugs at lists.freedesktop.org
        ReportedBy: fdo at colin.guthr.ie

Reproduce:
(with flat volumes enabled)
1. Set sink volume to something sensible.
2. Set event sound volume to something less than that, e.g. half
3. Mute event sounds
4. Run alsamixer -c0
5. Trigger an event sound.

Watch as the volumes adjust due to flat volume logic!

This can be an issue as if you have event sounds set to 100% and muted, but
sink volume to, say 60%, simply playing an event sound (which is muted) will
push the h/w volume up to 100% and leave it there.
