sound driver issues

I don't know exactly why or how, but I've had my sound driver suddenly stop working a couple of times over the past week...and I think this is related to my ongoing microphone issues.

problem is, I've already re-installed the sound driver for my laptop...3 times...hasn't fixed the issue.

any insight would be a great help in narrowing down my options for fixing this.

thanks in advance.

Take a look in your Device Manager and see if there are any yellow warnings.

Reboot your computer into safe mode and totally uninstall your sound driver. Then install the newest driver.

**EDIT**

Also, I'd like you to flash your bios to 2010-05-25 , Version:F.15,

ok, first thing's first.

tried the safe mode uninstall / reinstall, that makes 4 times with no change, still no response from either internal or external mics.

um....just being cautious, but why suggest a BIOS reflash?

device manager showed no issues, but the BIOS update DID fix the mic. it's working fine now.

thanks a bundle. ^_^

EDIT: whoops, when I checked in safe mode, the device manager was complaining about missing drivers. forgot about that. still problem finally solved
