Vista - Mic doesn't work unless i unplug, plug back in

Hello,

My microphone does not work after I reboot/start my computer unless I unplug it for about 5 seconds and plug it back in so RealTek can redetect it. Then it works fine until I shut it off or reboot the computer and then I must do it again.

I have looked on Google and I can't find anything, just other people having the same exact problem without fixes.

I have a BIOSTAR TA790GXB A2+ AM2+/AM2 AMD 790GX Full-Atx mobo from newegg right here: Newegg.com - BIOSTAR TA790GXB A2+ AM2+/AM2 AMD 790GX ATX AMD Motherboard - AMD Motherboards

I have the latest BIOS version as well. I used the BIOS update utility that came on the motherboard CD. I also have the latest RealTek drivers and have tried reinstalling several times. And like I said before, this was happening before I reformatted too, but strangely about 2 weeks before I formatted it just stopped happening and worked fine...... so strange.

Help please!

Thanks!

Make sure that your front audio ports are plugged into the motherboard, and are not loose.

They are, and I'm using the back not the front.
