Hey there, I'm trying to get my computer to output surround sound to my X41 (Surround sound headset) transmitter... I've plugged the optical cable between the 2, and the transmittor knows it's getting digital input, and I've told Windows in Control Panel that Dolby Digital is supported, so everything should be fine, but the LEDs on the transmitter indicate that it's decoding the audio with Dolby Pro Logic II... Which indicates it's receiving Stereo. It should indicate Dolby Digital, which is does when I use my 360 or PS3 with them. I tried playing CSS to see if it changed it, and putting the audio from 2 speakers to 5.1 to 7.1 didn't change what the LEDs said... What could be wrong? Cheers.
