Re: [PATCH] hda: Add dmux to STAC 9228

[Tim Gardner <tim.gardner@canonical.com>]

This doesn't seem to make a lot of difference. The external microphone
is marginally better, but still not really usable (recognizable but
distorted). The Gnome ALSA mixer shows 3 capture sources plus digital
and 3 mux's. Only the first capture source records anything. I verified
that you must have an external mic plugged in just to make sure the
built-in mic wasn't recording.
