Bug Description
[Impact]
This bug comes from OEM cert project of HP, the front mic jack can't detect
any plug/unplug, and we can't record any sound from plugged mic. This is a
block for OEM project.
[Fix]
The fix comes from Realtek, it is said that this is a power issue, after changing
the capability of the pin of linein, the power will keep being on for both linein
and front mic, then this issue is fixed.
[Test Case]
We tested plug/unplug detection and record through iphone/nokia type headset-mic,
all worked well.
[Regression Potential]
none, this is new added quirk, and only apply to the specific machine.
