My Acer Revo with Ubuntu Minimal Karmic, XBMC 9.11, and NVIDIA 190 Drivers plays multi-channel AAC with terrible audio sync issues. I have downmix to stereo selected and my hdmi cable runs straight to my TV.
Is this sync issue expected with this setup? Everything else plays perfect, even AAC 2.0, just not encodes with 6 channel AAC.
EDIT: Must have something to do with 59.94 FPS and AAC 5.1 being decoded by VDPAU. 29.97 FPS with AAC 5.1 works great.
Any help would be greatly appreciated.
Thanks!
