No sound left side

[ICantThinkOfAName]

I have audio in both headphones, but when i go to split/separate the sound using "main volume" in Realtek HD Audio Manager I doesn't work as it should. When I move the slider to the right, the audio stays the same. When I move it to the left, the sound fades in both headphones as if just turning down the volume.

The sound divider / separator / splitter or whatever it's called, works when I plug my headphones directly into the PC.

I am using new speakers. Actually the cheapest I could find on Ebay... The speakers are definitely the problem. Does anyone know of any similar problems being solved?

Thank you.

Any help would be greatly APPRECIATED as I can still get a refund on these speakers if it turns out they are just damaged
