Audio on Ultra5

Audio on Ultra5

[Simon Cozens]

I'm running UltraPenguin 1.1.9 with a 2.2.5 kernel, on an Ultra5, with
cs4231 sound as a module. However, after playing a couple of seconds of
the sample sound, it hangs, giving "pintr" "csr 0xc0042210 acr 0xc3bd2000
bcr 0" as kernel messages. (The csr seems to increase each time, the acr
stays the same.) This comes, apparently from the eb4231_playintr()
function in /usr/src/linux/drivers/sbus/audio/cs4231.c

However, I don't know why this is happening. I tried turning on
debugging and tracing, but this caused the kernel to panic impressively.
(As did upgrading drivers/sbus/audio/on last night's CVS snapshot)

aumix does this:
uks676:simon ~ % aumix -q
sys32_ioctl: Unknown cmd fd(3) cmd(40044dfe) arg(0002563c)
aumix:  unknown error 2: Invalid argument

but that's probably something to do with /dev/mixer not /dev/audio which
is causing the pintrs. Anyone seen this, beaten it, any suggestions?

(BTW, I'm not subscribed to the list, but I'll try and check by the
web interface. I'd appreciate a CC on any responses, though.)

undistorted to herself. To undistort herself, she finds Jack to distor her
distorted image in his distorting mirror. She hopes that his distortion of 
her distortion may undistort her image without her having to distort herself.

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.
