             Bug #: 54245
           Summary: Filter sinks (and sources?) that have an internal
                    buffer propagate rewind requests wrong
    Classification: Unclassified
           Product: PulseAudio
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: modules

Filter sinks that have an internal buffer add the internal buffer size to the
rewind request when propagating the request to the master sink. Instead of
making the request larger, the request should be made smaller, analogous to how
pa_sink_input_request_rewind() handles the data in the render_memblockq.

This probably doesn't cause user-visible problems, because the rewind requests
being larger than necessary only causes some extra rendering work and thus
higher cpu-use, the audio contents are not affected.
