Subwoofer won't work.

Specs: nice, nice

I have an Asus mobo with onboard AC'97 audio. For months i've had just two speakers connected two it, a pair of powered speakers that are plugged into the green line out port. They work fine. I also have 5 other speakers and a woofer left over from a broken amplifier so I figured I'd use them and plugged the woofer in (couldn't use the speakers because I haven't got the right connections).

I set the sound manager to 6 channel sound even though there's still only two speakers + the woofer connected since it was the only sound mode that included a woofer (aside from 8 channel sound). The sound test shows that the woofer and two speakers work fine. However in practice it doesn't work. I fired up a DVD that uses 5.1 channel surround sound and didn't get a whisper out of the woofer.

What gives?

I know having just a woofer and two speakers kind of deafeats the object of having it set to 6 channel sound but as I said I can't hook the other speakers up yet because I don't have the right connections. But even so the woofer should still work even though the other speakers aren't connected, right?

Are the speakers connected to the subwoofer and then to the pc or do you have them going directly to the pc.

The two speakers are connected directly to the PC via the green line out port (the left speaker plugs into the right speaker and the right speaker plugs into the computer), and the subwoofer is also connected directly to the pc via the orange centre speaker/subwoofer port.

I believe that may be your problem, usually pc speakers hook up to the subwoofer first and from the subwoofer you have two or three plugs.Usually a green, black, and organge depending on what type of speakers you have. Does your subwoofer have a place to connect speakers or little squars to connect wires.

No, it only has a port for connecting it to an amplifier. My amp that broke had all the ports on it for each speaker, I figured it was the same for the computer seeing as it has many different ports for different devices - It has six to be precise - one for the front speakers in 2, 4, 6 and 8 channel mode, one for the rear speakers in 4, 6 and 8 channel mode, one for the subwoofer and centre speaker in 6 and 8 channel mode, and one for side speakers in 8 channel mode. There's also a mic port and a line in port for an external sound input.

Is your subwoofer powered by an amp? If not, there is your problem. the outputs of most modern soudcards aren't strong enough to power a speaker all by itself.

No the woofer has it's own seperate power supply.

Okay, it's fixed now. It was really annoying me how it wouldn't work when it should do. SO I went back and checked the connections. I looked at them, and pushed them in but they wouldn't go in any further. So I unplugged the end on the computer and plugges it back in. Still nothing. So I unpluged the cable on the subwoofers end and then plug it back in and BOOM, the woofer nearly blew my ear drums out.

I played the DVD and it now works... Don't ask me why it didn't work before though. I have absolutely no f---ing idea. Anyway thanks for the help.

Hmmm, I don't think that it is going to work without an amp.

Well you're obviously wrong because it's working. The connection must have had crud in it or something, but it definetly is working.

I believe what you're thinking of are these cheap solutions you can get where you have just two speakers and a woofer, by which the woofer simply amplifies the bass from the 2 channel sound.

The sound card in my computer is an amp essentially. If it wasn't, it wouldn't have the extra ports for different speaker setups.

Anyway it doesn't mater now, since it works, and I'm happy.
