The unknown ioctl() is something that I've been meaning to look at for a while; I get the same problem with PCI sound cards (did davem fix this recently? It might have been in a patch somewhere, I'll check later). Aumix is horribly broken on sparcs anyway when you try to use its curses interface. try using it command-line only, or finding some utility like gmix if you're in X. -- Peter "Imagination is more important than knowledge." -- Einstein On Wed, 21 Apr 1999, Simon Cozens wrote: > > I'm running UltraPenguin 1.1.9 with a 2.2.5 kernel, on an Ultra5, with > cs4231 sound as a module.
