--- Comment #2 from skoupad-bugzi...@yahoo.com --- Additional info: As I suspected, the problem is most likely related to pulseaudio. Searching for a solution I stumbled across some bug reports on various distros that suggested to try inserting the following line to /etc/pulse/default.pa : load-module module-udev-detect tsched = 0 This indeed fixed the problem. But it messes up gnome sound so I can't use this solution. To my understanding the issue has to do with some problems in the alsa drivers and pulseaudio scheduler. Debian 8 uses an old version of pulseaudio and Debian 9 is just around the corner. Maybe the bug is fixed in the newer versions of pulseaudio. So, I don't know if this is actually a Kdenlive bug. -- You are receiving this mail because: You are watching all bug changes.
