            Bug ID: 763322
           Summary: directsoundsrc: program hangs on
                    IDirectSoundCaptureBuffer_Release
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

     GNOME version: ---

In my use case I use directsoundsrc to send audio via rtpmanager.
Seldom (between 15min - 5hours) while stopping the pipeline the directsoundsrc
will hang in IDirectSoundCaptureBuffer_Release() systemcall. This can only be
resolved by unplugging the soundcard (USB) if possible.
When watching the my process by sysinternals process explorer I see this stack
trace:
wow64cpu.dll!TurboDispatchJumpAddressEnd+0x6c0

Is there anybody out who has an idea how to debug or get more information about
this!? Or a place in the internet with people who might can help.
P.S: it confuses me why DirectSoundCreate is called, since I don't do audio
playback...
