I'm having minor problems with arts. I want to play stuff like
ogg123, xmms etc via arts (because my sound card doesn't sound very
good when used directly except for sound files at 48000 hz sample
rates, a bug in the driver apparently, but it sounds fine if I use
arts to upsample it). Now, this works fine except that both ogg123
and xmms coredump, with a segfault, when they stop. More exactly,
xmms coredumps whenever it reaches the end of a track, and ogg123
coredumps either when it reaches the end of the full playlist, or
when it's interrupted with ^C.
I tried running gdb on ogg123. GDB reports an illegal instruction
right at the beginning, backtrace as below, but this doesn't seem to
crash the program.

--------------
At the end, the program crashes, but I can't get a backtrace.
(ogg123, libao and arts are compiled with debugging symbols on, I'm
pretty sure the problem is in the interaction of libao, or the xmms
equivalent, with arts).
It says
--------------
Program received signal SIGSEGV, Segmentation fault.
0x281c94f0 in _IO_cleanup ()
(gdb) bt
#0 0x281c94f0 in _IO_cleanup ()
Error accessing memory address 0x281c94f0: Bad address.
--------------
So what do I do now? It's only an annoyance, not a major problem, but
it would be good to fix it. Or else, is there any alternative to
arts? esd -r 48000 sounds terrible, and I don't know of any other
sound servers.
(btw, this is the cvs version of arts, from the kde 2.2 branch.)
Thanks
