Just for the records: ION 2 is able to bitstream HD Audio formats. I've proofed that while playing with XBMCBunto Frodo RC3 on my Shuttle XS35GT. Unfortunately, this Shuttle hardware has other problems like many frame drops and stutter when running under XBMCBuntu and playing 1080p24 videos
Meanwhile I tried the Windows 8 way on this box. Perfect HD playback without frame drops and stutter. But now, I've also the problem, that the HD Audio formats are not recognized during HDMI handshake and so, I can't bitstream DTS-HD and Dolby TrueHD tracks.
My HDMI chain looks like the following: Shuttle -> AVR (Yamaha RX-V 18000) -> LG TV
What I'm wondering is, why the hell does this work with XBMCBuntu and not with Windows? If it is a general handshake issue, then I would expect this on XBMCBuntu as well...
