I'm about 20 years late to the game here. I recently finished Deus Ex and thoroughly enjoyed its use of 3D Positional Surround Sound while wearing headphones. (CMSS makes it even better.) To take advantage of this neat feature, your sound card must have an enabled onboard DD/DTS decoder and S/PDIF Passthrough must be disabled. 3rd-generation Sound Blaster Live cards (SB0220) and newer should have this. However, some OEM variants do not. OEM Audigy 2 ZS and X-Fi cards are notorious for lacking this feature.
I have just started playing Halo for the first time and noticed that it also supports this feature. Just set Hardware Acceleration to Yes and Sound Quality to High in the audio settings.
Are there any other games that also support this cool feature? I'd like to start a list of which games take advantage of this.
