I have a set of AV40's hooked up to my FRONT out on the Bravura and I just hooked up a BIC 10" sub to the sub out but I am getting no sound. I used a cable that looks like a headphone jack on one end and dual rca on the other. I found the sub only has a single RCA input. How do I get this to work?

One output on that cable will be the center channel and the other will be your subwoofer.
The subwoofer only has one in as it is only one channel. Set your card for 5.1 for testing. Connect the sub to the one side of that cable, run the sound test.
If you hear the sub you have the right connection. If you do not hear the subwoofer then you have to switch to the other output on the cable.

An issue you might have is most PC soudncard will not drive a true 2.1 audio system using the 2.1 setting. If you consider many PC audio system that are 2.1 they do not have dedicated sub inputs. 5.1 system have dedicated subwoofer inputs.
You may need to set to 5.1 to get a sub out from this card if you have a 2.1 system.

Ok, that worked but is it going to effect my sound for my AV40's if its trying to output to 5.1 with a center I don't have? I mainly just use winamp for music and play COD Modern warfare 2. I did just pickup a bluray player though.

Depends, usually for music the center just mimics part of the left and right channels anways.
This is a problem with many/most PC soundcards. There might be a few ways around it depending on your subwoofer. Do you have a picture of the back?

OK, what your going to have to do is wire the front left and rights out of the card to the subwoofer. Your speaker will connect to the subwoofer. Your card will be set for 2.0/2.1 the subwoofer will filter the bass from the left and right signal and send the rest to your speakers. This is how I would do it in your situation considering that limitation on PC soundcards.

Not sure how that would work. My sub has a single RCA input and that is all. It doesn't sound bad like it is. I think it might be ok considering almost all of what I listen to has no type of surround sound. I can't believe they don't give a true 2.1 option. Really lame. Looking forward to swapping these opamps out though!

Ok, so there are settings to get 2.1 sound and remove the center channel. You go through the setup for sound and choose 5.1 then you uncheck center and uncheck front sound... so you end up with 2.1 and sub control within the control panel. I found this on the Auzentech site

There are differnt ways to get the right signal routings. As I mentioned it seems to be a short sight on many PC soundcards.

Did you do the setup through the windows control panel - sound window or through the creative console launcher? i tried unchecking the center and rear speakers through the win7 CP - sound config and the subwoofer channel refuses to work. It starts working again only when all speakers are checked. Do you have this problem?

 

Btw, what subwoofer crossover frequency are you using? i'm using a pair of M-audio Bx5as as my speakers which bottoms out at a low end of 56Hz. Any recommendations for crossover freq?
