No sound from internal speakers on HP Laptop

Hi Experts,

We have a Windows 7 laptop giving us some issues.  It's relatively new and on a factory image of Windows 7 Home Premium.  A few days ago, the user stopped getting sound from the internal speakers.  Everything looks fine in the sound properties, nothing is muted, settings were restored to defaults, etc.  We also tried removing the sound card and letting Windows find it again.  That works fine, but no sound still.  We know the internal speakers work as we can get sound in tests outside of Windows.  We also get sound just fine if we plug in headphones.

Any ideas where to look next?

Thanks!

Or this may be a hardware problem with the switching in the headphone jack.

If the drivers don't fix it have a look at the socket - the contact that disables the speakers only has to move a short distance and if it gets bent the speakers are off permanently.

I guess internal speakers hardware issue as no option i can think of because the sound is OK if headphones are plugged in.

From control panel, check that the sound playback device is selected as speakers and not the headset

I dealt with that (or similar) issue a couple months ago.  The incorrect driver may be installing.  You should try downloading installing the audio driver from HP.com for that exact laptop.   This worked for us.

Good luck.

Still no luck thus far, trying to see if HP has any input.  If not, may have to try to reload the OS and see if it changes anything.

Tried that, still not getting anywhere.  Tried all above suggestions.  It seems like it's somehow related to skype.  The ONLY thing that will make sound is when opening Skype.  When you open Skype, you get the initial sound of Skype opening.  After that though, no sounds within Skype will work (calling out, etc).  Also, even if you disable Skype or boot into safe mode, there is still no sound anywhere else in Windows.

Tried uninstalling the audio device.  Tried reinstalling latest driver from HP, tried all settings in device manager under sound properties, etc.

Any ideas?

Actually it looks like Masqerade was right.  The socket looked fine but HP diagnostics thinks there is something plugged into the headphone jack.  Going to see if we can disable the headphone jack.

It actually looks like a physical problem. HP diagnostics shows headphones are plugged in all the time. Masqueraid looks to be right. The only reason Skype appeared to be related is because sound only works in Skype but upon closer inspection it seems to be because Skype is set to play sound effects through all speakers so its overriding the headphones locking out the main speakers.

then the only solutions i see are:
-poke with a needle in the jack - and try to open the contact
-replace the jack
