<div>I just received a new Texas Instruments eZdsp TMX320C5535 card. It is primarily a USB AC97 card with additional bells and whistles.</div>
<div><br>
</div>
<div>When I hook it up to Linux or Mac and use the OS interfaces (Sound Preferences, etc.) to select it, it plays and records sound quite nicely. Gstreamer sees it as the default sound sink and <i>gst-launch audiotestsrc ! alsasink</i> works as expected.
On linux is shows up as /dev/audio1</div>
<div><br>
</div>
<div>On linux, looking with aplay I see this:</div>
<div><br>
</div>
<div> $ aplay -l</div>

</div>
<div>When I use Gstreamer 0.10.28 with it, I get the following error:</div>
<div><br>
</div>
<div><br>
</div>
<div> $ gst-launch audiotestsrc ! alsasink device=hw:1,0</div>
<div> Setting pipeline to PAUSED ...</div>
<div> Pipeline is PREROLLING ...</div>
<div> ERROR: from element /GstPipeline:pipeline0/GstAlsaSink:alsasink0: Could not get/set settings from/on resource.</div>
<div> Additional debug info:</div>

<div> ERROR: pipeline doesn't want to preroll.</div>
<div> Setting pipeline to NULL ...</div>

<div><br>
</div>
<div>If I just shove some sound out to the device as seen in /dev, I do get output, sort of a choppy suare wave:</div>
<div><br>
</div>
<div> Gst-launch audiotestsrc ! Filesink location="/dev/audio1"</div>
<div><br>
</div>
<div>What am I missing here? </div>
