Hi Guys,

Before I ask my question, Just want to know if anyone here has had any
experience writing a driver for this device?

I am having some issues with the way the controller is behaving.

Hi Alex,

the asm source for such a driver can be downloaded here:

Hi Georg,

Thank you for your reply and the link. I had already looked at this code,
unfortunately is misses a couple of important things, like checking that
the PCR (primary codec ready) bit in the global status register before
starting the DMA. This is the problem I am faced with, as I'd like to do things
properly.

It looks like I may have to approach intel (and probably sign an NDA to
get any help).

Cheers
Alex.
