I searched on the problem IDT High Definition Audio Codec, which led me to DavidPK's solution posted 03202013 in re a HP EliteBook 8460p. I followed the direcitons therein, and got an error message also reported by MsChangey in 12 of 2013, "The hardware detected is not supported by this IDT software package. The install will be aborted. "
So, what is the proper fix? Do I need, and if so how do I get, the software package appropriate to whatever hardware is on this PC?
Windows 7 Premium OS. 64 bit.
