The sound card is a Sound Blaster Audigy MP3+ and the speakers are a Creative Inspire 5.1 system (don't remember exactly which anymore). When testing the system (where it says each speaker's name through the speaker) it all comes out just fine, and I can here the normal hissing/white noise through the center speaker when I put it up to my ear, indicating it's on and receiving signal. However, no application seems to be able to put sound through it. I noticed through some research that this may be indicative of some AC3 decoding problems, and so I tried tweaking those settings a bit to no avail. However, this may still be an open lead for someone who knows more about this area.
My computer's settings are set to use 5.1 speakers and not two or four, in both windows's audio configuration, as well as the Sound Blaster Audio Configuration panel. It remains configured this way, and switching between two and 5.1 does nothing except activate the rear channels.
Things I have tried:
-Installing drivers only
-Installing with only the software I want (these cards come with a boatload of crap)
-doing a full install (I had read somewhere that playcenter may be needed in order for this to work - seems like it should work out of box though - yet, it is creative - they aren't always in line with what should be)
-Installing a codec pack that I had installed before I reformatted and before I switched to 5.1, in case a fresh computer can't deal with 5.1 sound.
-Various other tweaks with settings
Any leads or information on what I may be missing now would be great. I'm starting to get into that circle where I've spent too much time debugging it and am having a hard time thinking of novel solutions. Thanks very much in advance.
