Located the problem the way dma was setup it used to stop after doing one frame. Here is the patch

Let me know if you see any issues in this.

Thanks,
Ashwin

I tried the audio driver from your tree at open nandra. It works if
i am running some audio file in CE and then boot linux. It did give some beep sound when I cat a file to the device.

Couple of things
1. this behavior seems same as your described some beeps being heard.
2. If i cat a large file cat seems to lock up.

Any ideas what might be the issue.
Thanks,
Ashwin
