Check your manual. Do you have a PF key or set of key strokes that deactivates the speakers?
Another problem can be with the headphone jack itself: This is what another person said:
The headphone input jack is stuck, there is a small switch inside the jack which shuts off the speakers when headphones are plugged in. When the headphones are pulled out, the speakers turn on again.
The thing you have to do is figure out which headphone jack you were using when you noticed this(i'm assuming you have 2 like mine).
My problem was that my girlfriend put an iPod video cable into my headphone jack to connect it to our stereo. It fits the hack but instead of a stereo 1/8" plug with 2 sections, it has 3 which makes it slightly longer which is what stuck the internal switch inside the jack and disabled the speakers.
Rather than bringing my computer to get fixed, I just took a pair of headphones and inserted them into the jack repeatedly, at different speeds. Mostly what worked was putting it in and pulling it out rather quickly. have a song playing looped while you do it so that you can tell if it worked or not. It will take some time and patience.
Thank you

I have an HP pavilion dv6920 and my headphones are not working. even if I put the headphones in, the sound is still coming from the speakers. Do you know what might be the issue? this happened right after I installed the software update on sounds (which was recommended by hp).
Many thanks in advance
Thank you so much for the advice it worked! It doesn't help when you're in the middle of playing a song for live performance and the sound jack won't budge. But yes Thank God for your willingnes to share.
