Here's a more detailed recap of the audio issue using XtrAIOS 3.0.11:
1) if the the input audio signal = 5.1/7.1 uncompressed hi-res audio, then:
a) hdmi audio set to 5.1ch/7.1ch sends 2.0 pcm signal to avr;
b) hdmi audio set to multi-lpcm sends 5.1/7.1 multichannel pcm to avr;
2) if the the input audio signal = 5.1/7.1 DTS-HD MA or TrueHD, then:
a) hdmi audio set to 5.1ch/7.1ch bitstreams DTS-HD MA or TrueHD to avr;
b) hdmi audio set to multi-lpcm sends 2.0 to avr.
Same results were obtained using a 5.1 channel flac file as well.
Again, the same results were obtained using the official and semi-official firmware. I think hdmi audio raw in the official and semi-official = 5.1ch/7.1ch in XtrAIOS 3.0.11.
There aren't many BRs with 5.1/7.1 uncompressed audio tracks but they do exist. Underworld, Underworld Evolution, and Replacement Killers have 5.1 uncompressed audio tracks.
Another thing I found using the official/semi official firmware was that pressing the skip forward (not fast forward) on my Harmony skips to the next chapter marker in the movie. With XtrAIOS 3.0.11, pressing skip forward (not fast forward) on my Harmony skips to the next movie on my drive.
The Pivos was able to play 24/192 2.0 and 24/96 5.1 flac files with no problem, unlike the PBO.
Hope this information is helpful.
