So I'm using a Turtle Beach X42 with my PC. I have a Z77 extreme 4 mobo and the built in sound card is supposed to support dolby digital live encoding. I am using S/PDIF connection to my headset receiver. My headset's receiver has a light that tells me Dolby Digital Live is being used. When using my Xbox, the light is on and I have glorious surround sound. However, when gaming on my PC, the light is off and I can tell that stereo is being used. In the Playback Devices > Realtek Digital Output > Properties > Supported formats I tested the Dolby Digital Live and the light came on and I heard the tone being played. When gaming, however, the light is not on. I would like to know what is wrong. The games I have tested are Arma 3, Crysis 2, Arma 2 OA, Planetside 2, and Team Fortress 2. At least one of these should support DDL encoding, but none work. I would really like to play using surround sound, and any help would be greatly appreciated.

Figured it out. Hopefully this will help anyone else experiencing a similar problem. I needed an external sound card that supported DDL encoding. Anyone else who has a headset that supports DDL surround sound, this is the solution if you aren't getting surround sound. Buy an external sound card (this is the one I bought, I got it refurbished though: http://us.store.creative.com/Creative-Sound-Blaster-XFi-Surround-5.1/M/B0044DEDCA.htm ) to encode the DDL signal over S/PDIF. If you have a Realtek sound card and you can't get surround sound on your headset, this will fix it.
