No sound from left speaker.

[ThundyCat]

So a weird one gents.

My daughters pc will not emit sound from the left speaker. If I plug my ipod into the aux port of the speaker sound works from both fine. If I connect from the front port headphone jack to the aux socket of the speaker windows sound from both speakers works fine.

Things I have tried so far.

Removed Asus DG and used onboard sound. Same issue of the left speaker not working.
Disabled onboard sound and used my second Asus DG to eliminate the first card being possibly faulty. Same issue of the left speaker not working.

Removed the DG and tried my Asus DX. Again same issue of the left speaker not working.

I have also checked to make sure the speaker balance is correct which is is.

My daughters pc is running Win 10
On a EVGA P55 FTW.

Basically I'm stumped.

Have tried a different 3.5mm cable. Have also as mentioned above tried 3 different sound cards, and I still get the same problem.

Wondering if it's a windows glitch/registry problem.

Well I tried headphones and sound was fine in both ears. So it would seem the left speak is duff when the 3.5mm cable is plugged into the back.

Thanks for the help guys.
