Hello guys! I just installed Deus Ex: Human Revolution on my Mac Mini 2011 and I'm having trouble getting the dolby digital sound to work. I have my mini connected to my home theater amplifier via an optical cable and the mini is running the latest Win 7.
When I launch the game I only get stereo sound. But in Windows I've tried the dolby digital test and windows plays the sound fine from every single channel so it's not a question of drivers(?). Any idea if this is a mac related issue (implying there's something about the hardware) or is this a universal problem with PC gamers alike?
Would appreciate any help, even an url to a helpful site would be much appreciated.
Unfortunately when I did research on this I found that games only support surround audio with a sound card that provides analog 5.1 output. The reason being that a game would have to do some processing to convert the audio channels into a Dolby stream and this requires a little bit of CPU as well as Dolby approval.
There are some sound cards that do this with onboard processing but then you might as well just get one with analog outs because you still have to get a sound card anyway. I'm not sure how OSX would react to having an unrecognised PCI card present. I'd be very curious to hear if anyone has tried this.
There are USB ones but in the long run is it worth all the trouble? I tried The Witcher 2 in surround with an elcheapo usb thing from China and it worked intermittently. It was enough for me to realise that the surround did not add very much at all.
There are usb surround headphones that might be worth exploring.
