Dolby TrueHD is a lossless audio technology designed for the new high-definition packaged media. Only Dolby TrueHD guarantees lossless HD audio playback from every HD DVD player and from supporting Blu-ray Disc players, and Dolby TrueHD also offers the most efficient lossless coding available. It supports up to eight channels (7.1-channel surround) of 24-bit/96 kHz audio, with expandability to accommodate more channels in the future while retaining compatibility with all Dolby TrueHD decoders. (For fewer than eight channels, Dolby TrueHD allows sampling frequencies as high as 192 kHz.) Dolby TrueHD gives content creators new capabilities to position sounds for the most realistic effects. And with audio playback that is bit-for-bit identical to the highest-resolution studio masters, listeners experience sound as stunning as the high-definition picture.

XFI的数字输出只支持Spdif Out

所以XFI不能支持Dolby TrueHD
