Fix audiovideo_PlaybackRecordSemiAuto on Snow.

Few notable difference for Snow:
Device name is DAISYI2S instead of HDA Intel, and capture
device name is DMIC1 instead of 'Capture'. And it's difficult
to tell playback|capture direction from some amixer control
content.
This change mostly changes the regular expression to make
audiovideo_PlaybackRecordSemiAuto work on Snow.
