Ok so I have taken the plunge and bought MC19 and so far I am very impressed with the video quality (my main reason for switching from XBMC), but I am still having some problems with audio, probably because I do not understand how things work. I had a good look at the audio advice page and I understand how that may be relevant to people using a computer to watch MC19 on but I am using a MacMini with bootcamp, linked to a Denon AVR-X3000 and I want to by=pass the sound card on the Mini completely and send all audio directly to the receiver. However, whatever I try the receiver keeps on telling me it is in simulated Dolby surround mode, even if I play films with DTS, 5.1 etc. multichannel sound. What am I doing wrong? I tried setting audio to Digital Audio HDMI Direct sound, but it makes no difference. Suggestions would be much appreciated.
