Audio Driver
But under Sound, Video and Game Controllers
This is what is blocking my update.
Conexant HDAudio Driver under Sound, video and game controllers in Device Manager and have file name uci64a96.dllthrough uci64a231.dll and a file version of 7.231.3.0 or lower.
I have a 7.217.0.0 with an uci64a217.dll.
