When using headset mic to record, the beginning of 2 seconds period is
not recorded.

Skip shutup routines for the codec. The shutup routines somehow
interferes headset mic recording.

External headset mic no longer records blank period once the patch is

[Where problems could occur]
Shutup routines are mainly for outputs like headphone and speakers.
Since the patch is using a rather generic match for both ALC236 and
ALC256, many systems might start to observe pop sound from the audio
