I'm trying to get full 5.1 surround sound, but the problem is...when I set it to run full 5.1 in the realtek HD manger window, I only get sound from my Sub and front speakers. I set it back to 24bit studio sound, it plays through all the speakers but the 5.1 sounds simulated. I am using an optical cable for this. I have the latest drivers that came out the other day. When I run the DTS test in my sound manager, i hear it through all the speakers, but as soon as I try to play music, it only does the 2 front speakers and the sub.
If my audio device supports DTS and says it supports Dolby 5.1, shouldn't I just be able to plug in an optical cable and go to town?
Is your music setup to be in 5.1? Generally it is just setup to be in stereo, in which case it will only use the front two speakers and send the low frequencies through the sub, it has no audio data for the remaining 3 speakers. Try a movie that supports surround sound.
Most games should be able to exploit the surround sound, they tend to have more dynamically generated audio tracks, movies and music have specific audio tracks for each channel and if it doesnt have the channel it wont send audio to it.
Most music is still mastered in 2.0. You could have a 24 speaker setup, but if the music is only 2.0, you'll only get music out of two speakers (unless you use something like Pro Logic to upmix at least).
