By trial and error, I found this patch could work around an issue where the headset mic would stop working if you switch between the internal mic and the headset mic, and the internal mic was muted.

It still takes a second or two before the headset mic actually starts working, but still better than nothing.

I'd like to add stable to this patch, but I'd like Kailang's ack first because I don't know what the verbs really do.

OK, I'll keep this pending for a day or two until Kailang's ack.

thanks,

Takashi
