... ok that was meant to be "the soundcard loses connection to the PC" ...

Hm, more strangeness.. Just by googling around it seems that the options are not exactly wrong, I think they are just not valid for the specific driver. The vid and pid is the vendor id and product id, and it's what you get from lsusb for example:

kane@xanadu:~$ lsusb | grep EDIROL
Bus 001 Device 005: ID 0582:007d Roland Corp. EDIROL UA-101

This option is in sound.conf in /etc/modprobe.d, which if understood correctly set explicitly the order of the internal HDA and the EDIROL:

kane@xanadu:/etc/modprobe.d$ cat sound.conf
options snd cards_limit=2

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel index=0 

alias snd-card-1 snd-ua101
alias sound-slot-1 snd-ua101
options snd-ua101 index=1 vid=0x0582 pid=0x007d

So if I'm not mistaken with "vid" and "pid" you can define exactly the device you want, as in the snd-usb-audio, at http://alsa.opensrc.org/index.php/MultipleUSBAudioDevices

So, in my case it doesn't seem to work.  After I commented it out, the module seems to load:

snd_page_alloc          7120  2 snd_hda_intel,snd_pcm 

and I finally have sound! Jack detects all the inputs and outputs and the card is working fine. 
EXCEPT that after some time and quite randomly (can be 1hr or 1min) the computer loses connection to the PC (the USB light on the card goes off), something which never happens in windows for example, so I guess it's a driver issue...

Any ideas about that?

Akis

Hm, yes that makes sense, that should be the alsa-base (or alsa-base.conf) file in /etc/modprobe.d ...

I'll check it when I'm back from work, thanx a lot...

I think you have a bad modprobe config file somewhere.  I forget where
Ubuntu keeps its modprobe options, but I suspect that somewhere you have
a file that says something like

   options snd_ua101 vid=xyzzy

instead of

   oprions snd_ua101 id=xyzzy

(I don't know what the id should be, but the parameter name is "id" not
"vid")
