I have an .mkv H264 video that starts with an a52 Stereo track, then switches to a 3F2R/LFE audio channel configuration. The moment it switches audio channels, the sound slows down by a factor of about 100…very demonic sounding. Kindof fitting for being an episode of True Blood (pre-show refresher is in stereo, then switches to 3F2R when actual show begins). I have AC3/DTS passthru set to disabled. I at least was able to play it in XBMC
i can confirm that bug, i got exactly the same issue for my favorite TvShow…
Hmm - can you submit a bug report?
