Sound Blaster Live! External: Would like some help please

[Jr Porkchop]

Hello,
         I was wondering if anyone has had success with the 'Sound Blaster 
Live! 24-bit External' USB Audio card, I have managed to get it initialising 
but i can't get it to produce sound.  I have produced a custom kernel with 
Ariff Abdullah's patch for RELEASE 6.0 to the /usr/src and used:
device       sound    # Loads generic sound for headers
device       snd_uaudio  # Loads USB audio
in the kernel config.

The model number is SB0490.  I also run KDE 3.4 if that could be also 
causing a problem.

Here is some debug stuff as I have been reading a lot in this forum and is 
always asked for;

Any thing else needed for helping you diagnose my problem I am happy to do 
but I'm new Unix and I'm just looking for help.
