Re: Issue with Intel HDA Sound card 82801G (laptop Medion)

[Tobin Davis <tdavis@dsl-only.net>]

Sorry about that.  Had a final project for class last week that took all
my time (had to watch O' Brother, Where Art Thou ~20 times, pulling
clips, snapshots, and quotes - yuk).  I don't have another class until
10/31.

>From your last email, it looks like your laptop is configured as a
3-stack system in Bios:
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
autoconfig: line_outs=3 (0x14/0x15/0x16/0x0/0x0)
speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
hp_outs=1 (0x1b/0x0/0x0/0x0/0x0)
inputs: mic=0x0, fmic=0x18, line=0x1a, fline=0x0, cd=0x0, aux=0x0

It's possible that you need a gpio to enable output, similar to acer,
but using gpio2 instead of 1.

Try applying this patch, then changing th model to
"model=6stack-dig-demo"

This should enable everything.  Send me the output
of /proc/asound/card0/codec#0 and dmesg (make sure to compile with
debug=detect like last time).
