Hi Joe,
My BIOS version was recently updated to 2014.0522.1323. I do have the chipset drivers installed - version 9.4.0.1027 per the Intel driver update utility. For my audio driver it says "Intel(R) Display Audio. The driver version is 6.16.0.3137. The note below this says "This device is unknown or unsupported. Please contact the manufacturer for possible updates."
It's a little disconcerting that the Intel driver utility concurrently says that I have the Intel driver installed and also that the device is unknown or unsupported. How is this possible? Is this an indication of the issues I'm having?
