I've been getting a kernel oops with the latest CVS (as of today). I've
attached the output from ksymoops. I CAN get it to re-occur. Running
Smurf, loading up a sound font, and playing a bunch of notes eventually
causes Smurf to segfault, with the kernel oops in my system log.

Aggh.. I just ran a whole bunch of ALSA latencytests with various
drivers/kernels, all with fairly bad results :( I even went back to my
older kernel (2.4.5 with Andrew Morton's patch
from Joystick port) is the front output, which will probably act more
like what you want. Sometime an ALSA SB Live FAQ should be written, its
taken me a while to get used to all the quirks.

one?
Thanks in advance to anyone who has some info or solutions to fixing

believe this is the case though, but to be honest don't
really know how an application would get scheduled to wake up once ALSA
is ready to send/receive a chunk of audio.

Yeah, I think it was mentioned (on alsa-devel) that this is fixed in
ALSA CVS? New kernel ioctls changed so you'll need to check out CVS to
get it working.

work all nice and sweet :) Is this function call required in a program
to synchronize PCMs or can this be done externally (asound.conf?).
Looking forward to vocoding and doing other cool real time PCM effects

I have an SB Live! and it works fine BTW. If you want to figure out what
an error is use snd_strerror.

than looping part of the buffer again. I might be wrong about all this,
so someone who really knows about ALSA XRUN handling should then step in

Its not very general at the moment perhaps a real full-duplex test
program should be written for distributing with ALSA?
For detailed information uncomment the #define
documentation, although we still suffer from more general overview docs.
Perhaps they don't know about the doxygen stuff, and this would quite
some complaints?
