I have just booted to the rc2 with the patch (https://lkml.org/lkml/2011/6/9/25)
and it looks it didn't solve the problem. Playback works only from
speakers when headphones are not plugged in - no sound if plugged in.
See alsa-info.txt-fresh-boot. Same thing happens if I
modprobe -r snd-hda-intel and then load it again (without any parameters).

If I try to modproble with model=auto I get headphones working but not
output from speakers. Have a look at alsa-info.txt-modprobe_auto.
