Re: Audio on Ultra5

[Peter Jones <pjones@redhat.com>]

The ioctl() problem and the aumix problem are probably pretty unrelated to
the csr/acr problem.  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.
