Hello,
I am on an iMac ("*imac-20" model/pinconfig) with a Intel HD card with
the SigmaTel STAC9221 codec. I have attached the inital codec info
after modprobe. When I plug in and then unplug my speakers the
microphone stops working. Reproduction steps with codec dump diffs as
follows
1) Initial codec info - attached - Microphone working
2) Plug in speakers - Microphone working
Node 0x0c [Pin Complex] wcaps 0x400181: Stereo
Pincap 0x081737: IN OUT Detect
Pin Default 0x9017e110: [Fixed] Speaker at Int N/A
Conn = Analog, Color = White
- Pin-ctls: 0x00:
+ Pin-ctls: 0x40: OUT
Connection: 1

3) Unplug speakers - Microphone not working
