I've got all of my audio issues worked out now, except for this one issue which makes boxee almost useless for me. The vast majority of my movies I've encoded with mp3 audio tracks to save space.
I'm using Ubuntu 8.04. I've got xbmc install on this same machine and everything works fine with it. I don't have any audio issues at all. I have it configured to output digital audio out, with ac3 and dts pass through.
AC3 and DTS passthrough work properly. Music works properly. Streaming video from sites like hulu work properly. The only problem is a rhythmic popping noise as I play mp4 video with mp3 audio tracks. I can hear the mp3 audio in the background too. However the popping noise is quite loud, which prevents me from watching the movie.
I'm not getting errors in the log. Can anybody suggest a way to debug this issue?
