             Bug #: 53915
           Summary: Filter sinks call pa_sink_process_rewind() needlessly.
    Classification: Unclassified
           Product: PulseAudio
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: modules
        AssignedTo: pulseaudio-bugs at lists.freedesktop.org
        ReportedBy: tanuk at iki.fi

Filter sinks have this in the beginning of their pop callbacks:

    /* Hmm, process any rewind request that might be queued up */
    pa_sink_process_rewind(u->sink, 0);

There should never be any rewind requests pending when the pop callback is
called, so this is a useless call (pretty harmless, though). Fixing this should
be trivial (just remove the calls), but I think there should be some testing
done before pushing the fix, which is why I'm filing this bug instead of just
fixing it.
