[SOLVED] JACK not working on an HDA Intel card (ALC888)

I'm trying to get JACK working on my Acer Aspire 5930G which has got this Intel HDA onboard audio card.
My JACK configuration is in this screenshot: http://i.imgur.com/DmqV2.png

And this is the output from JACK:

22:35:32.132 JACK sta partendo...

I tried loading it in a tty (supposing it was some problem related to KDE) and I saw the very same error except for one curious kernel log string:

...
ALSA: final selected sample format for playback: 32bit integer little-endian
ALSA: use 3 periods for playback
[ 7621.516546] hda-intel: invalid format_val, rate=44100, ch=10, format=10
ALSA: cannot set hardware parameters for playback
ALSA: cannot configure playback channel
...

If I try to run JACK in capture only mode it starts, in playback mode it doesn't. Finally, when I put plughw:0 as an output device it's all working, but when I'm using Reaper via Wine audio suddenly locks up (I'm guessing due to some big xruns) and I have to close it and restart JACK to make it work again.

Can somebody help me?

EDIT: Solved by using this module options in my /etc/modprobe.d/alsa.conf

options snd-hda-intel model=acer-aspire position_fix=1 enable=1 index=0
