I recently replaced my motherboard from an Intel DP67BG to an Asus P8Z68-V Gen3. One problem I noticed is that in the Windows 7 starting screen, my speakers will pop for a second, and this pop is just before the Windows 7 default done loading sound. There is no audio popping during audio playback. I'm using Creative T20 Series II speakers. This popping when Windows starts loading didn't happen on my previous motherboard. Is this just a bug in the motherboard's onboard audio drivers or does my motherboard have a defective audio chip?
