Hi.

I chatted on IRC yesterday. I'm having some issue(s) with ALSA. I
want to stream aac. xmms2d will set up the chain successfully but
then not produce sound.

Under various circumstances I've gotten xmms2d to hang/spin on two
different code parts as observed with strace.

The first is a loop with nanosleep(1 sec) and
read(/dev/snd/controlC0) which always returns -EAGAIN. This
could possibly be in xrun_recover() but I haven't confirmed that.

The other is a strange spin with futex() ioctl() semop() and I think
one more system call.

DrK on vanilla 2.6.23.9 with built-in alsa and OSS emulation.

Using oss output works fine, but is not as cool.

nano, tilman? How can I get useful debugging output from alsa.c?
If you send me a debugalsa.c I'll build with that and report back.
-v produces nothing useful.


//Peter
