Windows 7 - No sound from right headphone-hp pavilion dv6

Any headphones I plug in to either of the two ports, the right headphone doesnt work.
i tried with different headphones none of them work ( new or old ones.)
when i try plug the headphones on others pc and laptop,both right and left side is working fine
external speakers work well.
sound balance settings is at 100 and when i press test button i hear from two headphones.
But the problem is, the left headphone is the only one I can hear out of when fully plugged in(when playing audio or video)

maybe there is some sound setting problems,
or any updates that caused this problem,
i set it to default but still i got the same problem,
there is no sign that i missing my sound driver in my device manger.

I'm running a 32 bit Win 7

Can anyone tell me what I should do to fix this problem?


(The odd thing is it was just fine with one of my headphones a few minutes ago but now nothing!!!
its not working again.
i'm desperate.)

Malakeh,

I have had this happen to me. I know of no software settings that can configure sound to come out of only the right or left side of a headphone, unless you are testing it for sound. Have you tried plugging in regular speakers? My guess is it would have the same result as the headphones. For me, the cause of this was the jack itself. You might have a rear and forward headphone port (green), so try them both to see if one or the other is working/not working. What I mean to say is, perhaps the jack itself is broken.

thanks alot

Are you sure you are inserting the headphone plug fully? If it's only partially inserted you will only get sound from one side.
