Sounds like you have an interesting problem with your nvidia sound device.
Is the audio device a part of a graphic card by any chance?
Sounds like the graphics is interferring with the audio device, though
on puredyne the rtirq-init script together with the realtime kernel
should give higher priority to the audio device even when sharing irq
with other devices, if this is the source of your problem.
Perhaps Alsa would be interested to know of this problem? You could
subscribe to their mail list and let them know.

Here are the Creative Labs devices supported by Alsa:
