Hi, I don't know whether you remember this topic, so I give you link to archives [1]. I don't know how did it happen that I didn't see reply in my mail client. I ran pulseaudio with -vvvv and I noticed [so late!] that Workaholic uses SDL. But this is not the only source of problems. Another source of problems is high CPU usage (by Firefox etc), which causes PA when playing to interrupt. When watching a Flash video online, a little sound made even by libcanberra can cause few-miliseconds pauses and "jittering" (?) in playback (you know - a "jumpy" playback). Stdout output from pulseaudio -vvvv [2] when Banshee playing, Workaholic started and closed and some sounds made by libcanberra.. I really hope you can help me, because I tried many configurations and nothing helped me resolve all issues. 1| https://tango.0pointer.de/pipermail/pulseaudio-discuss/2008-December/002763.html 2| http://paste.jabbim.cz/3008 -- Best regards, Jakub 'Livio' Rusinek http://jakubrusinek.pl/
