Desktop speaker issues

post #1 of 3
Thread Starter 

Hey all, this is my first post. I'm REALLY unsure if this is the right forum for this or not, and I apologize if this is indeed the incorrect forum for this. 

But anywho, I'm having this weird issue with my computer's sound. 

 

Motherboard: msi 785gm e51

The sound is integrated. I was suspecting that since a simple two speakers have never worked properly with this computer, always just one working, that the integrated sound card was borked. This didn't bother me and I dealt with having one speaker. 

Fast forward to today, when I acquire two eighteen inch sub-woofers and a number of smaller surround sound speakers. Perfect time to hook everything up and enjoy it, right? No not really. I hook everything up properly to my receiver (which I've had work fine with seven speakers when the sound is from CD player to receiver), and alas, only one speaker works again. So yeah, it's probably my sound card that's messed up and I need a new one.

So I grab my laptop, hook the receiver up to it, and suddenly sound is coming from one speaker, again. But this time it's the left speaker that has sound, not the right. 

This has me utterly confused. I can't figure out what's wrong. Hooked up to my desktop, only the right from speaker works. Hooked up to a laptop, only the front left speaker works. I'm new to this sort of stuff, but I really don't know what's wrong. What should I do? I'll try to provide as much information as possible. 

TLDR: Only one speaker works, out of seven. Speakers all work fine when receiver is not hooked up to the computer but to a CD player. Sound switches from speaker to speaker when switching computers.

Have you tryed a diffirent cable?, and checked the pc sound settings check you haven't selected mono anywhere or you music files aren't in mono.

You are probably using an Y-cable from headphone out to 2x RCA.

Check it is indeed a stereo plug and if possible measure the connection between the pins of the RCA and the tip and ring of the 3.5 mini plug.
