>Description:
	With the addition of the appropriate line to auich_devices table
in auich.c the onboard audio seems to mostly work.  Two things aren't quite
right:

1: The outputs.master volume control does nothing.  Instead, outputs.surround
works as the master volume control.

2: I'm getting occasional "auich0: fifo underrun # 1" errors.  This may be
because the audio player isn't actually feeding the data to the audio card
fast enough.  However, if I intentionally cause audio data starvation
by, e.g., playing audio across the network and running "ifconfig down"
and "ifconfig up" at various timings, the device will sometimes get in
to a confused state and play the audio with a lot of stuttering and
echo.  Triggering another fifo underrun fixes the audio.

>How-To-Repeat:
>Fix:
	Probably search the intel docs for what is different between the ICH5
and the other audio devices.
