Okay, i've done a little bit more investigating...
Weird thing #1: tuxkart works fine, even when i'm playing other sound.
Also, I checked both sawfish and gnome (these being what i'm running) and
they both have their sound stuff turned off. Still no go on AQFH...
Weird thing #2: Well, I'll let you figure out meaning of this since I'm
not really sure what it's telling me...
A snippet from "strace tux_aqfh" where things appear to start going wrong,
as near as i can tell (I've fiddled with formatting for readability but
the data's 100% accurate, copy/pasted):
==SNIP==
ioctl(8, SNDCTL_DSP_GETOSPACE, 0x83045ac) = 0
write(8, "\200\200\200\200\200\200\200\200\200\200\200"..., 4096) = 4096
ioctl(8, SNDCTL_DSP_GETOSPACE, 0x83045ac) = 0
write(8, "\200\200\200\200\200\200\200\200\200\200\200"..., 4096) = 4096
ioctl(8, SNDCTL_DSP_GETOSPACE, 0x83045ac) = 0
write(8, "\200\200\200\200\200\200\200\200\200\200\200"..., 4096) = 4096
ioctl(8, SNDCTL_DSP_GETOSPACE, 0x83045ac) = 0
write(8, "\200\200\200\200\200\200\200\200\200\200\200"..., 4096) = 4096
ioctl(8, SNDCTL_DSP_GETOSPACE, 0x83045ac) = 0
write(8, "\200\200\200\200\200\200\200\200\200\200\200"..., 4096) = -1
EAGAIN (Resource temporarily unavailable)
write(2, "slDSP: write: Resource temporari"..., 47) = 47
ioctl(8, SNDCTL_DSP_GETOSPACE, 0x83045ac) = 0
write(8, "\200\200\200\200\200\200\200\200\200\200\200"..., 4096) = -1
EAGAIN (Resource temporarily unavailable)
write(2, "slDSP: write: Resource temporari"..., 47) = 47
==SNIP==
Runtime-wise, this happens shortly after the game opens /dev/js0, if that
helps any. This is also the first time in the strace that the program
writes to file handle 8, which is what open("/dev/dsp",...) got.
Right now this is looking really odd to me, but then again I don't have
much experience coding for sound ;)
Thanks for your help,
Chris Willis-Ford
