Do I need a new sound card?

post #1 of 16
Thread Starter 
First, Merry Xmas to everybody.

I received a pair of Klipsch pro media 2.1 speakers today, but I am getting no sound from the sub woofer at all. I have Realtek onboard sound and when I am setting up my speaker setting Windows 7 gives me no option for 2.1 set up, nor does the Realtek HD audio manager.

I get the options for 1) Stereo, 2) Quadraphonic, 3)5.1, 4) 7.1.

I tried stereo first then I tried selecting 5.1 and 7.1 and disabling all the speakers but front two and sub woofer but I still get nothing at all from the sub at all.

Did you turn up the subwoofer knob?

You should be selecting stereo for the setting.

There is no setting for 2.1. Because the only signal is from a left and right stereo signal. The amp on the speakers will then just send those same signals to the subwoofer.

Just turn up the subwoofer volume knob. Adjust your equalizer as well.

The sub woofer knob only increases the bass output of the two desktop speakers.

Hmm...if you put your hand on the subwoofer, do you feel it shaking? If it's shaking, then it's working. If you can't hear it, then I think it might be that you have it in a location that's not prime for placing a subwoofer. Subs are usually placed in the corner of a room so that it carries to the rest of the room.

In that case, the subwoofer may not be properly hooked up from inside the box. I would return them and get a replacement.

You should double check the following on the sub:

- The power switch on the back
- The stereo connection wires (color coded red/black) which come from the right speaker
- The DIN cable which also comes from the right speaker to the sub
- As the other post said, also make sure the sub volume on the right speaker is set to half way.

Hopefully its one of those things. Let us know!

The sub or speakers have no power switch oddly enough. They just turned on when I plugged them in. DIN cable is in and I re did the other wires just in case. I put my hand up on the sub while playing music, the vibrations in it were very minute and I think its probably from the desktop bass running through them.

That is very strange, because i have the same system and there is a rocker power switch just slightly above and to the left of the power cord (which is at the bottom of the unit). Its actually very easy to miss and I have to feel around to find it. I know this sounds insane, but could you triple-check around the back of the sub for a rocker switch. Once on, the sub will be making a quite "humming" sound.

The newer Promedia 2.1 sets don't have power switches.
