Comment 23 for bug 1284466

If I plug a microphone into the mic jack then hda-jack-sense-test -a shows it plugged in. e.g.:
david@fink:~/Downloads$ sudo hda-jack-sense-test -a
Sigmatel specific "Analog Loopback: 0x00" verb ignored for the moment
Pin 0x0a (Black HP Out): present = Yes
Pin 0x0b (Not connected): present = No
Pin 0x0c (Not connected): present = No
Pin 0x0d (Internal Speaker): present = No
Pin 0x0e (Black Line In): present = Yes
Pin 0x0f (Black Line Out): present = No
Pin 0x10 (Not connected): present = No
Pin 0x11 (Not connected): present = No
Pin 0x12 (Not connected): present = No
Pin 0x13 (Internal Mic): present = No
Pin 0x14 (Not connected): present = No
Pin 0x21 (Black SPDIF Out): present = No
Pin 0x22 (Not connected): present = No

I am not sure why I am getting more output now than before. How can I clear the misc bit?
