Hi, for what it is worth I've always had better luck using oss with sb16 cards. You have to configure everything on that card and at the moment I don't have the settings I use handy but I can certainly dig them up. It was something like: modprobe sb insmod sb irq=5 io=0x0220 dma=1 dma16=0 Like i said I'm not sure totally, but that is a start.I'd have to find my old modules.conf file to get the exact settings.
