[David Henningsson <1256840@xxxxxxxxxxxxxxxxxx>]

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.
