[Alsa-devel] patch, and other via82xx (VT8235) capture problems

[Zinx Verituse]

I've attached a patch to fix a bug in the via82xx driver,
but I suspect the register is wrong for the VT8235 because
when I set the Input Source to 'Mic', no interrupts seem
to be getting triggered:

arecord: pcm_read:1110: read error: Input/output error

But as 'Line', it works (albeit with significantly reduced voltage and volume)

Are the specs for the VT8235 available anywhere?

Useful info:
Kernel: Linux 2.6.0-test7 (patched bug exists in CVS tree, too)
On-board sound card: 00:11.5 Class 0401: 1106:3059 (rev 50)
Motherboard: A7V333-X
