Thinkpad speakers not working

We have a Lenovo T500 that has no output from its speakers.  Sounds play fine through headphones or external speakers.  They are not muted, and if we bring up the equalizer, you can tell that it's recognizing the sounds.   We've tried the following:

Reinstalling the Conextant driver.
Updating the BIOS.
Reinstalled SNDVOL32.EXE

Any thoughts?

There are people having intermitent issues with sound on the T500/T400's recently.  Unfortuntely there is no for-sure solution at this point.  People have tried updating the BIOS, reinstalling drivers, etc.. to no avail.  Below are a few solutions that did work for some people and a link to the lenovo forum if you haven't already visited it..

1)  
Using Windows XP, here's the solution that worked for me:
1) Download the driver: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70595
2) Go to device manager -> audio -> right click, install driver, don't search -> pick "sound, video..." have disk -> direct to driver at: c:drivers/win/audio/xp32/***.inf

2)
 Instead of waiting weeks on a round trip to factory for repair I opened her up. I found a pinched internal speaker wire near a screw for the palm pad on the right side. I also double checked and made sure the speaker cable connector was seated well. Once I put it back together and restarted, my internal speakers and sound were alive and well.

3)  
I upgraded from Vista to Windows 7 and the problem went away.  I now have sound again.
It is using the Microsoft HD Sound driver.  I am afraid to install the Conexant driver.

I'm leaning towards the hardware fix, ie. cable pinch.  If the headphone jack works, doesn't it make sense the that driver is correct?  I did replace the Conextant driver.
I would agree.  If you are able to get to it, checking the physical wire connection to the speakers would be my best guess.

Soon as I can get the user to give it up, I'll check it out.  Thanks for the suggestions.
