Actually, the only ioctls which needed to change were the ones to set up which audio device you get; The others were always present. I presently lack xmms but if you'll set me strace output I'll be happy to look at the problem. That I know of current 2.3 kernels still aren't up to snuff on sparc32, though I may be wrong. That said, I only have sparc32 machines, so I haven't exactly been able to do any work on this in a while. In my 2.3.5 machine I'm able to use x11amp and it works fine. -D
