About week ago I made nearly same patch but Jernej pointed me to this
one. I applied this patch and it works like one I made.

Audio output works fine, but recording doesn't work at all in my tests.
I can hear myself from microphone on headphones quite fine but 'arecord'
records only some kind of white noise. Tried all alsamixer widget
combinations but didn't managed to record anything.

Kind regards
