            Bug ID: 103498
           Summary: Closing PulseAudio freezes SDL audio
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: core

This is a slightly weird bug. When using SDL mixer (1.2) to play music on 32
bit x86 Linux boxes, things works perfectly most of the time. However every now
and then things break down when closing down the SDL audio device.

The actual freeze happens inside PulseAudio. SDL's deinit calls into PA, which
does a pthread_join that never returns. When this happens if there is an
another SDL sound player it keeps on working perfectly. Trying to open a new
SDL audio player fails. Restarting PA fixes the issue so new music players can
be opened, but it does not work reliably.

Detected with PA 5 but replicated as well with PA 10.
