Hiya:
Unfortunately the 2.2.x kernel that RHat 6.0 ships with doesnt quite access your SBLive. You have a few options, if yours isnt a mission critical computer, and have access to a decent enuff connxn speed, get yourself Rhat 6.2, the kernel jump should be able to get your SBLive working [i dont remember the kernel version documentations, off hand - even though I just used it earlier today .. thats age for u
], hence I'd suggest doing step 2 or at least being aware of it, for the future as well...
the ALSA project is a wonderful collection ..
www.alsa-project.org
bookmark it and read the documentations and how to get your environ audio drivers for sblive working.
Cheers
