I get no sound in headphones or speakers, Inspiron 5150, Sgma Tel Audio

Question

I have tried all troubleshooting available.  All obvious settings are correct.  The sound was working fine then 'poof', no sound at all. I have recently installed some work related software but it should not have affected the sound.  I am hoping it is not the motherboard, it is a work laptop and it won't be replaced just for sound issues.  If anyone can help, I would greatly appreciate it. Thanks, ST   02.03.05 - I thought this might help in diagnosing the problem - Recently I have been hearing some static from my on board speakers, still no recognizable sound though.

The sound card is integrated with the motherboard so I sent my laptop back to Dell (it was still under warranty) and they switched out the motherboard.  I have to say I was impressed with the service, I shipped it out on a Friday after 4pm and received it the following Thursday morning!  Sorry folks, it appears the only solution is replacing the motherboard! :'(....  Thanks Again! ST......................

I think I've got a solution...

I have an Inspiron 8600 and a friend has an 8500. Both of us have experienced this problem. It has occurred to both of us when we inserted the plug from our headphones into the speaker-out jack on the computer. In the headphones you hear a "static zap" and zappo, the sound is dead. I tried it once with the sound playing though the laptop's speakers, inserted the headphones, the sound became low & distorted in the headphones (had to crank all volume levels and could only hear soft/distorted sound), pulled out the headphone plug, and the sound was still low & distorted.

I fixed the problem by updating the BIOS (the first time it happened, I updated the BIOS to the latest version, then the next time it happened, I just re-ran the same version update... I think there is an ESD problem with a static zap to the speaker-out jack somehow zapping the system's BIOS NVRAM. Since others have fixed the problem by running the Dell diagnostics program this seems to confirm this. I wouldn't doubt this program examines errors in the BIOS and resets it.

Any other thoughts out there?
