           Summary: alsasink broken with hw:X or when used with either
                    alsasrc or osssrc
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED

On Fedora Core Rawhide. 
 That plughw:0,0 works but hw:0 does not may be a Fedora problem

> gst-launch-0.8 sinesrc ! alsasink device=plughw:0,0
* Works fine

> gst-launch-0.8 sinesrc ! alsasink device=hw:0
RUNNING pipeline ...
ERROR: pipeline doesn't want to play.

* No sound. 
* for export  GST_DEBUG=*:5  see attached

> aplay -D plughw:0,0 /usr/share/sounds/info.wav
Playing WAVE '/usr/share/sounds/info.wav' : Signed 16 bit Little Endian, Rate
44100 Hz, Mono

* Works fine

Playing WAVE '/usr/share/sounds/info.wav' : Signed 16 bit Little Endian, Rate

aplay: set_params:859: Channels count non available

* Fails with No sound 

Mplayer ( recompiled from freshrpms/dag SRPMSs ) works everyway
>  mplayer -ao alsa:device=plughw#0.0  /usr/share/sounds/info.wav
>  mplayer -ao alsa:device=hw#0  /usr/share/sounds/info.wav
>  mplayer -ao oss  /usr/share/sounds/info.wav

* Works fine, no anomalous error messages

With Gstreamer alsasrc or osssrc works OK if the sink is osssink
> gst-launch-0.8  alsasrc  device=hw:1,0 ! osssink device=/dev/dsp
> gst-launch-0.8  alsasrc  device=hw:1,0 ! osssink device=/dev/dsp1
> gst-launch-0.8  alsasrc  device=plughw:1,0 ! osssink device=/dev/dsp
> gst-launch-0.8  alsasrc  device=plughw:1,0 ! osssink device=/dev/dsp1
> gst-launch-0.8  osssrc device=/dev/dsp1 ! osssink device=/dev/dsp
> gst-launch-0.8  osssrc device=/dev/dsp1 ! osssink device=/dev/dsp1

* All of the above work Ok, outputting auto and returning at ctrl-break with
RUNNING pipeline ...

Execution ended after 39 iterations (sum 7453782000 ns, average 191122615 ns,

However  alsasink with device=plughw:0,0 outputs utter silence.
