[linux-audio-user] jack trouble

Well, I'm always trying to get midi audio recording working, or at least 
just one of these :)    ; well, I'm trying very hard but .... nothing's 
working  ; I'm trying since a long time but .....

I have a P4 computer and mandrake 9.2 with a low latency kernel ( 
2.4.22-21mm.2mdk).
Well alsa is running and when I launch alsaconf, it says that my sound 
card is "intel 8x0 Silicon Integrated Systems [SiS] Sound Controller"  
(in fact, sound is integrated in the motherboard (an Asus P4S8X-X), and 
the motherboard doc says that the chip is an ADI AD 1980 6-channel audio 
codec) ; in an another place, I've also seen SiS 7012...... Alsaconf 
don't perform the last thing, playing a song 'cause something is missing :

    Loading driver...
    /usr/sbin/alsaconf: line 568: rcalsasound: command not found
    Setting default volumes...
    ===============================================================================
                                                                                                 

     Now ALSA is ready to use.
     For adjustment of volumes, please use alsamixer or gamix.
                                                                                                 

     Have a lot of fun!

                                                                                              



So I'm trying to launch jack and, as root, I type #jackd -d alsa -r 
44100 and here is what I get :

And I'm obliged to do a Ctrl C to stop the process and Iget the mess :

    jack main caught signal 2

When switching verbose option for starting jack, jackd -vd alsa -r 
44100, I get also thiese lines :

So, nothing is working neither muse, nor rosegarden or ardour or 
.....anything else

Last thing when I perform lsmod, iget this :

Well if someone have any idea, it would be nice to get this working ; I 
really need to make music with linux, I don't want to be obliged to run 
my atari falcon with cubase audio until the end of time !!! But, really, 
I don't know what to do....


cordialement,
