My g4's headphone could only produce sound on one side. So i bought a new headphone jack from ebay and replaced it. The problem still persists. Does this mean it could be a motherboard issue?

Or a headphone issue. You did try a different pair of headphones?

Great! My headphone port couldn't hold my headphones anymore because of wear & tear (they kept falling out) but this guide and a 6 dollar ebay-item fixed it! Thanks a lot.

I just replace my jack but problem still persist.

Headphones work with app call'soundabout' so problem is not on software. So what cousing this? When i plug headphones nothings happen? Also i dont see any damage on motherboard eveything seems perfectly normal.
