Alexander, you rock!  :-)  After applying two tunables suggested I finally
have working playback and recording (I've patched hdac_widget_pin_patch()
function directly to avoid doing a reboot), huge thanks!

I'm having an almost forgotten feeling of something getting quite obvious
after being explained.  I will try to prepare a patch for manpage as I
know there are others complaining that while it's very thorough and
detailed, it often fails to help in real life (e.g. in my case, I could
not come up with proper patch for nid9).

Thanks again,
