AAC encoding (ISO/IEC 13818-7 standard) was public available since year 2006. I will found very difficult to believe that your receiver can support AAC decoding being so old that it don't has HDMI inputs. In this scenario, even if some day Xbian includes AudioEngine/PulseAudio with AAC digital passtrough capabilities, your receiver will receive the same as today: PCM stereo.

DTS is a different scenario. As an older standard than AAC your receiver obviosly has to support it. So I cannot figure why your adapter is no letting pass digital streams of that kind. Could do you log via SSH and paste here the results of the following command? All your setup (RPi, adapter box, receiver, tv) must be connected and on.

/opt/vc/bin/tvservice -a
