[Alsa-user] Support for ALC671 codec

[Rainer K. <Rai...@ts...>]

Hi there,

working on a new mainboard platform I experience some sound related 
problems with the ALC 671 codec that my new mainboard uses.

Problems are:
- front panel mic is not working, you can't select a capture source
- rear line-in is not working, you can't select it as a capture source
- the system speaker is not working either, there are no mixer controls 
for it

I tried several tools to get a clue what is wrong:

- codecgraph complains:
Codec: Realtek ID 671
Node 0x22: Amp-In vals count is wrong: values found: 7. expected: 1

hda_analyzer doesn't work:
# ./hda_analyzer.py /tmp/alsainfo.txt
