Missing support for via VT8237 and ALC655

Missing support for via VT8237 and ALC655

[Niccolo Rigacci]

Hi!

I have a motherboard based on the VIA KT600 Northbridge and VT8237 
Southbridge. The codec is an ALC655.

I tried the ALSA module snd-via82xx. PCM audio works fine, but several things 
did not work:

- The MIC input does not work, no matter how I set alsamixer
  controls (the OSS driver via82cxxx_audio, instead can properly
  mix the input).

- Capture does not work. I tried to enable capturing from MIC,
  LINE or CD, but no stream is received by arecord. Also OSS
  emulation (/dev/dsp) does not receive any data. I tried to
  set, unmute and caputre any control in alsamixer.
  The OSS dirver via82cxxx_audio can't capture too.

Just to check, on the same system I fitted a snd-maestro3 PCI card, which 
works perfectly mixing and capturing any audio source.

Is there some developing on that VIA chip? Can I do some tasks to help testing 
or coding?

Thanks

Make a report to your bug-tracking system.

Of course, to our bug-tracking system. Sorry for typo :-)
