[alsa-devel] help with idt 92hd206 codec for intel hda?

[Nathan Schulte]

I recently purchased an ECS A740GM-M Motherboard which has also an IDT
92HD202 integrated audio chipset.

ALSA is recognizing it as a SigmaTel 9221 A2.

I'm willing to test these patches as well as give any information you guys
might need.

(sorry for any duplicate messages, I'm still trying to get hold of how this
listing thing works...)
