Sound missing R channel

[eknirb]

So here’s a tricky one. The sound on my Windows 7 HP PC began acting up. I seem to only get sound from R channel..when they’re properly connected.
I have two brand new Bose speakers set up on my desktop, and the one on the right has four plug ports: Power / Aux/ Connect to computer / Connect to left speaker. All those are connected properly.
So if I pull the ‘Connect to computer’ cord OUT of the speaker most of the way, IE, leaving it barely in there, I get sound from both speakers. Although I’ve noticed in audio playback, some songs sound like they’re missing something. For example, the intro to the Association’s “Along Comes Mary;” it sounds to me- I swear- like a layer of the opening guitars are now missing.
It’s not the headphones, which I plug directly to the speakers. They are brand new hi-end Sonys, and work fine when plugged into a mini-DVD player.

Any ideas? TY!

Make sure that the speaker cable at the back of the computer hasn't worked its way loose. You could also try plugging the headphones directly into the back of the computer in the speaker port to see if you get both channels that way.

It could be your speaker connection cable, or a hardware fault in the computer.

Another thing to check would be the Sound control panel, and make sure that the balance setting on your level controls hasn't been accidentally set all to one side.

Thanks for the response- everything was connected properly. Now, it seems to be working just fine. Who knows?

A connection could have been dirty and just needed to be reseated. It happens. Glad you got it working.

I was thinking maybe a bit of dirt in there or something. the sound from these Bose's is really nice. TY for writing.
