Hi again I would just like to report that im pretty sure i found the cause of the problem.
I tried to compile a tarball version of asterisk to solve the problem, but that didn't help. So working with #asterisk on freenode they put me on the right track: the timing source. Atleast for my selfcompiled version it helped to put the following entry in modules.conf: noload => res_timing_timerfd.so This is the default timing module in linux, since it's the fastest, but apparently it doesn't work properly in debian squeeze. So by not loading it, asterisk fallback to another one of its timing modules, and then playback works. Hope this helpås somebody and enables the maintainer to fix the bug Med venlig hilsen / Best regards Jonas Akrouh Larsen TechBiz ApS Laplandsgade 4, 2. sal 2300 København S Office: 7020 0979 Direct: 3336 9974 Mobile: 5120 1096 Fax: 7020 0978 Web: www.techbiz.dk<http://www.techbiz.dk>
