>Description:
	nForce 420D audio doesn't work with auich(4). (dmesg shows many
	'codec is not ready' errors)
>How-To-Repeat:
	% audioplay anyaudiodata.wav
>Fix:
	This patch enables MCP-D analog audio on MSI MS-6367 mobo.
	line-out (headphones-out) and mic-in was tested, both OK.

	XXX man auich/auich.c say 'mic-in is not supported', but some
	people (include me) can use mic-in! XXX
