sorry, I do not know.

1. But you should provide more information. Use `alsa-info.sh` [1] to do
this.

I hope someone else reading this list has experience with Xilinx and may
help you. But I doubt it.

2. Anyway, did you contact Xilinx about this?
3. Can you try a live image of a different GNU/Linux distribution (for
example KNOPPIX) and see if it works.
4. Did you try a newer ALSA version?


Thanks,

Paul
