yea, i have red hat 8.0 i have the same problem. i have an onboard sound, and sb live. inboard is disabled in the bios, but rh still picks up both of them. i cant play any sound. however, even when the onboard is disabled in bios, i get a looping sound through the onboard after boot? its really weird and i couldnt figure it out.

whatever it is they havent fixed from 7.3 to 8.0

if anyone has any suggestions please let me/us know
