Hi Takashi, Steven, et al, My apologies for not getting back to you earlier. I applied the short patch to the hg-20080502 snapshot. That seems to have done the trick. All of the different analog output channels are now available, as well as a bunch of input channels. I only tested output, but that seemed to work. I will hopefully be able to test the inputs this weekend. Given the discussion that I saw, it looks like I won't bother with the digital output. Thanks very much for your help on this. -Greg

Hi all, I recently acquired an ECS GF7100PVT-M3 motherboard, which appears to

the IDT 92HD206 codec for HDA. Unfortunately, it doesn't appear to

Analog

inputs.
I found the tech specs for the chip at http://www.idt.com/products/getDoc.cfm?docID=13461840 I've attached an lspci output and the codec file to this email. I'm
not
much of an driver hacker, but if someone could give me an idea of what
needs
to go into the patch_sigmatel.c file to make this thing work, I'd be
willing
to try. I'm also more than willing to test out patches on my setup.
The below is an entirely untested patch quickly made from the codec information you posted. Could you give it a try with the latest ALSA HG version?
Steven informed that this codec is compatible with STAC927x. So the revised patch below is dramatically shorter. Try this one instead of the previous one.
thanks,
Takashi
