Hello everyone,
I've been having this problem with huge FPS dips at scene changes during playback of certain shows (mostly cartoons) that result in stuttering playback and muted audio that eventually catches back up to the video. I tracked it down through trial and error to being an audio setting causing the problem.
When i first boot the system and launch xbmc this is what the audio output device selection looks like:
The available selection are limited to what is shown here and pulseaudio, custom is not an option.
After i quit xbmc and re-launch this becomes available:
After changing this setting my FPS issues disappear. This happens under eden and frodo, KDE and unity, ubuntu 12.04 and 12.10, as well as debian sid. It happens with pulseaudio and alsa, gstreamer and vlc phonon backends. What is happening here? How do i force xbmc to use the 2nd setting at all times? I've tried manually specifying the audio device listed via aplay -l and even that does not solve my FPS issues, only the exact steps above do. After a reboot this all starts over again.
Thanks for any help!
