I'm no specialist in sound, I've got sound output as HDMI and 5.1 speakers, I can set audio value while watching these shows so I guess no passthrough.

there are almost no AVRs supporting passthrough for AAC. they can decode AAC, but not receive it as passthrough. that's why XBMC is doing live transcoding of AAC into AC3 when playing. all XBMC versions but RPI. no CPU power. but maybe will be managed later as hw supported AAC -> M LPCM.

so currently you get stereo only. for such media files I put it through ffmpeg - adding additional AC3 track to the file. all original streams are just demuxed and muxed back with additional audio track. takes 2-3 minutes and video quality is untouched.
