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

3) Unplug speakers - Microphone not working

I guess you can restore the status via toggling "Line In as Output Switch" and "Mic as Output Switch" mixer elements. The problem looks like the unsolicited event handling. It doesn't cope with the shared input jacks well.

In case my guess is correct, the patch below should fix the problem. Give it a try.

Glad to hear. I committed to ALSA tree now.
