Just a heads up to anyone that wants a cheap solution to get DH on your PC. There's a few of the Plantronics Gamecom 777 usb adapters on ebay from around $9-$15 shipped and it does do DH. I have had the dongle since I bought that headset a couple years ago and works fine (never really used it since I mainly game on consoles).
Side note: This dongle processes audio to DH only by going from Dolby Pro Logic II -> 5.1 -> Dolby headphone. This is something I just realized when I was reading into it today. This only accepts 2 channel audio and there's no way to set it up to take in a pure 5.1 audio stream. But for the most part, it still works fine when testing this with the 5.1 mix of Gunbuster and setting the output as DPLII with ac3filter.
nice find but there has to be a way also to get that dongle to do ddl---> 5.1 dolby headphone because that chip thats inside the housing of the dongle is the same chip that the mixamp uses go figure!
Just imagine if someone could do a hack to get that to work you would have a very inexpensive mixamp minus the chat though for consoles..
