[alsa-devel] Intel HD SigmaTel STAC9221 - Wrong input after output change

[Ivan N. Zlatev]

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
      0x03


3) Unplug speakers - Microphone not working

Node 0x0b [Pin Complex] wcaps 0x400181: Stereo

     Conn = Analog, Color = Unknown

     Conn = Analog, Color = White

   Connection: 1
      0x03
 Node 0x0f [Pin Complex] wcaps 0x400181: Stereo

4) Plug in speakers again - Microphone not working
