Hi, The PulseAudio backend in OpenAL Soft is in really bad shape. Some apps, like MPlayer, will simply hang if openal is used, others, like the game Warzone 2100 starts, but runs with no sound. Unfortunately, the openal-soft developer does not use pulse, and isn't sure what the problem is: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548373#33 Is there anyone out there who feels like beating the pulse backend back into shape? :-) I'm attaching a backtrace from the MPlayer hang if it's of any help. -- Cheers, Sven Arvidsson http://www.whiz.se PGP Key ID 760BDD22 -------------- next part -------------- Thread 2 (Thread 0xb4d3fb90 (LWP 12012)): #0 0xb80da424 in __kernel_vsyscall () No symbol table info available. #1 0xb617d467 in *__GI___poll (fds=0x89c0dd8, nfds=2, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:87 resultvar = <value optimized out> oldtype = 0 result = <value optimized out> #2 0xb7c315b2 in poll_func (ufds=0x89c0dd8, nfds=2, timeout=-1, userdata=0x89c0c70) at pulse/thread-mainloop.c:75 r = <value optimized out> __func__ = "poll_func" __PRETTY_FUNCTION__ = "poll_func" #3 0xb7c1e2d2 in pa_mainloop_poll (m=0x89c0bd0) at pulse/mainloop.c:879 __func__ = "pa_mainloop_poll" __PRETTY_FUNCTION__ = "pa_mainloop_poll" #4 0xb7c1fb03 in pa_mainloop_iterate (m=0x89c0bd0, block=1, retval=0x0) at pulse/mainloop.c:961 r = <value optimized out> __func__ = "pa_mainloop_iterate" __PRETTY_FUNCTION__ = "pa_mainloop_iterate" #5 0xb7c1fbd4 in pa_mainloop_run (m=0x89c0bd0, retval=0x0) at pulse/mainloop.c:979 r = <value optimized out> #6 0xb7c31363 in thread (userdata=0x89c0bb0) at pulse/thread-mainloop.c:94 mask = {__val = {2147483647, 4294967294, 4294967295 <repeats 30 times>}} #7 0xb5ea1db2 in internal_thread_func (userdata=0x89abb08) at pulsecore/thread-posix.c:72 __func__ = "internal_thread_func" __PRETTY_FUNCTION__ = "internal_thread_func" #8 0xb7f064b5 in start_thread (arg=0xb4d3fb90) at pthread_create.c:300 __res = <value optimized out> __ignore1 = <value optimized out> __ignore2 = <value optimized out> pd = 0xb4d3fb90 now = <value optimized out> unwind_buf = {cancel_jmp_buf = {{jmp_buf = {-1208918028, 0, 4001536, -1261177864, -574802118, -1701675716}, mask_was_saved = 0}}, priv = {pad = {0x0, 0x0, 0x0, 0x0}, data = {prev = 0x0, cleanup = 0x0, canceltype = 0}}} not_first_call = <value optimized out> #9 0xb6187a5e in clone () at ../sysdeps/unix/sysv/linux/i386/clone.S:130 No locals.
