I recently upgraded my debian stable (lenny) OpenAL to openal 1.9.563. I started getting: Inconsistency detected by ld.so: dl-close.c: 718: _dl_close: Assertion `map->l_init_called' failed! Some google searching led to this thread on debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=551018 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=551018#22 says: There are some issues that occur when using pulse as the backend driver for openal. For one, an application using openal will either hang (in the case of mplayer) or will not have any sound (in the case of warzone2100 and supertuxkart). This message appears in the terminal for each application. AL lib: pulseaudio.c:370: tlength (14544) is not a multiple of minreq (4096)! Second issue is mainly with mplayer. Aside from mplayer hanging, mplayer also always exits with this message. Inconsistency detected by ld.so: dl-close.c: 719: _dl_close: Assertion `map->l_init_called' failed! Setting openal to not use pulse will not give these issues. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
