Hi!!! I have a sound blaster live 5.1 to listen dvd videos in 5.1 config. When I see a DVD, the outputs are all right. but when I listen music, MP3 for example, the only active outputs are front L/R. Thats OK, but I have a 18" sub with a 450W RMS amp and I want to use it. So, I go to Surrounder, I enable sub output & bass redirection, and the sub output goes to FRONT speaker. its like i have to switch front/sub if i want to use mp3 playback. what's wrong?? :hmm: Thanks!!!!! ps: i love this driver!!!!!
