Description of problem:

aplay and gstreamer fail with 
a) ALSA output device set to hw:0
b) ALSA output when using OSS or ALSA input

See GStreamer for bug details.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. gst-launch-0.8 sinesrc ! alsasink device=hw:0
2. aplay -D hw:0,0 /usr/share/sounds/info.wav
3. gst-launch-0.8  osssrc device=/dev/dsp1 !  alsasink device=plughw:0,0
4. gst-launch-0.8  alsasrc device=plughw:1,0 !  alsasink device=plughw:0,0

Actual Results:  Depending on the command used. 
#1,#2 Consistently return error message 
#3,#4 Just output silence

Expected Results:  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

Comment 1 Martin Stransky 2005-01-05 13:54:53 UTC 
Is plughw:1,0 input device? You don't have to use hw:0 directly, it is
hardware of your sound card and it probably don't support many
wave-formats directly.
