Anybody know how to get 5.1 sound from XBMC when playing AAC 5.1 format. For DTS I can get 5.1 but AAC 5.1 I only get 2.0 sound from my HT.

hi guys,i need some advice here.Recently i am starting to keep some untouched bluray BD-ISO but sadly to say my AC Ryan HD Mini2 does not seems to be able to play the ISO image file,so as for my Sony S380 BDP.
I however do have a PC which i want to use for my HT which is not the best performance but is an AMD dual core 3.2GHZ CPU,4 GB DDR RAM & Gigabyte HD5670 GPU with HDMI out.
So what software or player do i need to playback the BD-ISO which can bypass the HD Audio and let me Denon 4311 AVR do the decoding of the DTA-HDMA/Dolby True HD to my 5.1 system?
I am planning to hunt for an Oppo BDP93 but currently this is all i have,please help.Thanks

I just plug in my Apple Mac Mini using  XBMC to run BD-ISO on my HT system and for those who are new,here is some settings you need to do on the OS X settings.
1. Go to system preference -> sounds ( there will pop up a window box and first setting is sound effects,choose the ' play sound effect through' to your AVR name
2. Go to Output and select your AVR name
3. Go to XBMC and in the audio settings choose Audio Output to HDMI

Then we are all set to enjoy decoded DD 5.1 from AVR.

One thing I am not sure is why it can't decode DTS-HDMA as my ISO has the audio imbedded on it? Can anyone explain what I am missing?

I connect my PC via hdmi to my avr(yamaha aventage series). I used mpchc + madvr setting & LAV. My graphic card is nvidia 550ti. In LAV, I checked to bitstream all audio options. Let's say I play a video with 2 audio channel, then my avr will decode the audio to 5.1 channel. But I can just play the original audio in 2 channel too. Just pass thru(bitstream) the audio and play with your avr settings.
Hope this help.

hmm bit quiet here eh, i've been visiting time to time see if got ppl create new discussion hehe
btw my current setup is very simple, my player is vlc on my laptop
laptop > wolfson 8501 DAC > Powered Edifier M3300 + Edifier P3080M (only sats from my M3300 attached to the P3080M to increase the mid range) > another out on Wolfson goes to my Wharfedale PMX500 Powered mixer/amp > Robertson Audio silver 25 tower speakers

For movies i only use the edifiers, for music i use all the speakers

Thinking in future will upgrade to the X-LS Encore series by fx20, by a forumner here

Forgot mention i also have a dedicated active wharfedale sub really old one for the bass side during watching movies, it also acts as a passthru to my wharfedale pmx500
