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... 22:35:32.133 /usr/bin/jackd -P89 -p128 -dalsa -dhw:0,0 -r44100 -p256 -n3 -H -M -Xseq jackd 0.121.3 Copyright 2001-2009 Paul Davis, Stephane Letz, Jack O'Quinn, Torben Hohn and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details could not open driver .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory 22:35:32.142 JACK è stato avviato con PID=25878. could not open driver .so '/usr/lib/jack/jack_net.so': libcelt0.so.2: cannot open shared object file: No such file or directory JACK compiled with System V SHM support. loading driver .. apparent rate = 44100 creating alsa driver ... hw:0,0|hw:0,0|256|3|44100|0|0|hwmon|hwmeter|-|32bit control device hw:0 configuring for 44100Hz, period = 256 frames (5.8 ms), buffer = 3 periods ALSA: final selected sample format for capture: 32bit integer little-endian ALSA: use 3 periods for capture ALSA: final selected sample format for playback: 32bit integer little-endian ALSA: use 3 periods for playback ALSA: cannot set hardware parameters for playback ALSA: cannot configure playback channel cannot load driver module alsa 22:35:32.169 JACK è stato fermato con successo. 22:35:34.208 Non sono riuscito ad avviare JACK come client. - Operazione fallita. - Impossibile connettersi al server JACK.

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

There's no place like 127.0.0.1
