GStreamer | gst-plugins | Ver: 0.8.6

           Summary: alsa output doesn't work with dmix plugin
           Product: GStreamer
           Version: 0.8.6
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: jtl at schlund.de
         QAContact: gstreamer-bugs at lists.sourceforge.net


Using software mixing with alsa, the gstreamer alsasink stops after a tiny
amount of time (<1sec) playing (gstreamer-properties reports
"gstreamer-properties: pcm.c:2094: snd_pcm_wait: Assertion `err == 1' failed"
before the program aborts, also all other gstreamer based programs abort with
this message.)

See the attached asound.conf for my alsa config. This config works with xmms,
xine, mplayer and other alsa stuff without a problem.

Removing the software mixing makes alsasink happy again. It doesn't help to use
only output software mixing (I tried it with a config where I don't use the
duplex stuff, but got the same result).
