Hi,
I want to use the JACK soundserver. I'm able to connect to the normal
analog output but not to spdif.
I use the snd-intel8x0 driver for my onboard nforce2 soundchip.
ash-2.05b# cat /proc/asound/devices
1: : sequencer
0: [0- 0]: ctl
18: [0- 2]: digital audio playback
25: [0- 1]: digital audio capture

24: [0- 0]: digital audio capture
33: : timer

Using the alsa output plugin in xmms I can choose hw:0,2 then the
sound comes out through spdif, but I don't know how to do this with
JACK. I tried qjackctl (grafical controller for JACK and ALSA) and
qjackconnect(grafical patchbay) and via console by typing 'jackd -d
alsa -d hw:0,2' (same with hw:1 and hw:2) but this doesn't work,
neither as user nor as root.
via console I get the following output:
ash-2.05b$ jackd -d alsa -d hw:1 -S
jackd 0.98.1

Is there some special configuration needed in '/etc/asound.conf'
Please help me, if it works I want to write a howto in the gentoo user
forum cause there is to little information about JACK and JACK is
definitly a great leap forward considering the sound quality.
