Okay, well so much for the running to speaker systems at once idea. Anyway, I've just recently stumbled upon a new problem (if it truly is one or not I'm not sure yer). I have my 5.1 Sound Blaster Live card, and I have my Microlabs 4.1 speakers hooked up to it. When I run the EAX test in Surround Mixer to test all 4 of my speakers, I only hear from the Front Left and Front Right speakers...Not the Rear ones. But, when running programs, games, and movies, I can some-what hear out of the Rear speakers. Is there something I'm doing wrong here?

You should try and set the speaker volumes for the ones that you can barely hear to more volume (if the software has that option)and dont worry if the test doesnt detect the other 2 speakers, if games and music etc give u the sound then you shouldnt worry

Try going to audio headquarters|speaker and making sure your system is set for 4 and not 2 speakers. This is a common problem with SB.
