At some point audio stops working (all input/output set to pulseaudio). Just know, I started pulseaudio from the command line. I start skype, hear the swoosh sound, go to settings, click test sound a few times, then do test call. At that point, pulseaudio aborts: [root@otto ~]# N: alsa-source.c: Increasing minimal latency to 1.00 ms N: alsa-source.c: Increasing minimal latency to 2.00 ms N: alsa-source.c: Increasing minimal latency to 4.00 ms N: alsa-source.c: Increasing minimal latency to 8.00 ms E: source.c: Assertion 'pa_cvolume_compatible(volume, &s->sample_spec)' failed at pulsecore/source.c:666, function pa_source_set_volume(). Aborting. How reproducible: Don't know yet; skype has failed playing sound at least twice. Googling for the error message didn't turn up results. Also, the line number is suspicious; Lennart, is The Beast hiding in your software ? Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: In my opinion, pulseaudio crashing because of a bad client should be a no-no. Throwing out the client would be ok; and it should somehow be able to tell me about the bad client. pulseaudio is meant to run as a server, and it was by accident that I noticed the message.

It happens when I make the test call. Judging from the method, it might be related to the setting that allows skype to control mixer levels, which I will deactivate for the next test. - after that happens, skype cannot play any sounds at all anymore. - skype also can't be shut down. A normal kill doesn't work either. kill -9 does it though. - installing debug symbols now to get a backtrace of the assert.
