How to get DTS/Dolby Digital output from games?

post #1 of 4
Thread Starter 
I have a Radeon HD 5800 card and I'm using the HDMI port, it outputs DTS and Dolby Digital. If I watch a movie with DTS it will show up on my receiver.

If I play a game (such as Battlefield 3) it always shows up as "PCM Multi" .. I've been trying to get DD/DTS enabled while gaming but I can't figure it out. Is there a setting I need to change or something? The only setting I've found was changing the speaker configuration in the control panel from headphones to 5.1.. that changed it from 2.0 to 5.1 but it didn't enable DTS/DD

Thanks

I don't know that much about audio, if I'm getting "PCM Multi 5.1" on my receiver is that basically the same thing as DD/DTS?

Yes, you are already getting proper surround sound with your games. Game audio is rendered in real-time, so with HDMI you can get the final multichannel mix as uncompressed PCM rather than relying on an extra lossy DD or DTS encoding step.

DVDs, on the other hand, are not real-time sources and come with audio tracks already encoded in DD or DTS that can be bit-streamed directly.

In other words, you are good to go.

you are fine, just make sure your sound device is configured for 5.1, 7.1 if you have it and not 2.0
