The error Assertion 'b' failed at pulsecore/memblock.c:451, function pa_memblock_acquire(). Aborting. is happening about every other run of a particular app (Dragon Age Origins) for me now. I am running ubuntu 10.10 on an i7, and dpkg-query says pulseaudio is version 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu21.1 But this isn't just an ubuntu problem, and it's not specific to the app I'm running, or even to wine; see also http://bugs.winehq.org/show_bug.cgi?id=23163 https://bugzilla.redhat.com/show_bug.cgi?id=630895 https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/492136 There seem to be two workarounds: 1) run the app in question under "taskset 1" -or- 2) put enable-shm = no in ~/.pulse/daemon.conf After doing the enable-shm=no workaround, and then removing it, the problem seems to have gone, too. So it seems to be flaky. Does any of this ring a bell? Thanks, Dan
