Description Tanu Kaskinen 2012-08-22 11:45:53 UTC
pa_sink_input_request_rewind() contains this:

    i->thread_info.rewrite_flush =
        i->thread_info.rewrite_flush ||
        (flush && i->thread_info.rewrite_nbytes != 0);

The "i->thread_info.rewrite_nbytes != 0" doesn't do anything useful, so all it does is create confusion (it's otherwise harmless).

It would be good to test the change at least a bit before pushing. I'm not willing to do that right now, which is why I'm filing this bug.

Removing unecessary check

The patch just remove the i->thread_info.rewrite_nbytes != 0 check.

I've done the follow tests:

1) Moving the sink-input around two different sinks a bluetooth device and my sound card.
2) Cork/Uncork the sink-input in the bluetooth sink
3) Several volume changes

In all these three tests worked as expected.

The bluetooth device used was: Motorola EQ5 portable speaker.

Best Regards,

Hey folks, is it necessary other tests to validate it ?

Thanks in advance,

No, the tests that you've done are fine. The patch is pushed now, sorry for the delay. I changed the commit message a bit to align with usual conventions. Thanks for the patch!
