Exact steps for others to reproduce the error
Having selected OpenAL for Sound in the user preferences, and opening for example the default cube .blend file, click on play in the timeline, or press Alt-A.
**FIX
Choosing any other Sound mode in the user preferences proved a workaround for me.

It seems like there's some trouble with OpenAL + pulse again, can you get a gdb backtrace of the crash with a debug build of blender?
nexyon,
hi, sorry for the late, follow up.
how exactly do I go about getting this gdb backtrace (I'm not a developer). Ive got it installed but never used it. Also, I need build a debug version of blender? normal build from my distro repos doesn't include debug features?
Yes you need a debug build of blender. The wiki has all details about that, including how to get the gdb backtrace: http://wiki.blender.org/index.php/Dev:Doc/Tools/Debugging/GDB
Any news on this here? It has been a while!
