Mono... Why'd it have to be mono!?

[Super Cameraman]

First off, mono as in only one speaker working.

For some reason, only one of my speakers is working with my computer. I though, well they're old, and I replaced them. Now I think it's a problem with my computer because even when headphones are plugged in, only one works. Does anyone know how to fix this problem? I am okay with opening up the computer, and I think that's the problem. Could it be software? Or the speakers even though I know it's not?

Try updating your drivers for whatever sound card you have. Also try buying a new soundcard. If that doesnt fix it, I'm not too sure what will.

Also try new speakers. Maybe the whole speaker is messed and only outputs mono.

If only one speaker works, then there's a good chance your jack is worn out. That happened with our old Optiplex, so we soldered a new jack on. I don't recommend doing that if this is your primary computer we're talking about. The easiest thing to do is buy a new sound card.

I second the bad jack hypothesis.

Before getting a new sound card or doing any soldering, you might try playing some music or something noisy on your computer and just moving the plug around in the jack. If the jack is going bad, usually you can wiggle around the plug and make contact well enough to get patchy stereo sound.

This would confirm a bad jack diagnosis.

I don't think it's a bad jack because the same thing happens with the headphone jack in the front.

In that case, it sounds like it's most likely either your sound card isn't working or you just set your stereo balance all the way to one side.

Or maybe you're just deaf in one ear...

sounds like your sound card is blown

Id check all your software settings, and if not, then completely remove/reinstall the driver before you give up on it.
