Can't pipe sound to new TI C5535 device

[Wesley J. Miller]

I just received a new Texas Instruments eZdsp TMX320C5535 card.  It is primarily a USB AC97 card with additional bells and whistles.

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  gst-launch audiotestsrc ! alsasink works as expected.  On linux is shows up as /dev/audio1

On linux, looking with aplay I see this:

   $ aplay -l
   **** List of PLAYBACK Hardware Devices ****
   card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
     Subdevices: 1/1

   card 1: U0x4510x9010 [USB Device 0x451:0x9010], device 0: USB Audio [USB Audio]

and

   $ aplay -L

When I use Gstreamer 0.10.28 with it, I get the following error:


   $ gst-launch audiotestsrc ! alsasink device=hw:1,0
   Setting pipeline to PAUSED ...
   Pipeline is PREROLLING ...
   ERROR: from element /GstPipeline:pipeline0/GstAlsaSink:alsasink0: Could not get/set settings from/on resource.
   Additional debug info:
   gstalsasink.c(499): set_hwparams (): /GstPipeline:pipeline0/GstAlsaSink:alsasink0:
   Rate doesn't match (requested 44100Hz, get 0Hz)
   ERROR: pipeline doesn't want to preroll.
   Setting pipeline to NULL ...
   Freeing pipeline ...

If I just shove some sound out to the device as seen in /dev, I do get output, sort of a choppy suare wave:

   Gst-launch audiotestsrc ! Filesink location="/dev/audio1"

What  am I missing here?
