Intel has just released (Beta currently) new Graphics Driver to finally enable HD Audio Passthrough, which previously has not worked on any Intel Windows system: I cannot enter link but if you go to Intel Download Center, Drivers & Software and search - Intel® Beta Graphics Driver for Windows® 10 and Windows 7*/8.1* [15.40] - it will find it. (note the description suggests it is to enable Battlefield and Fifa17 but this is a much wider fundamental HD Audio Passthrough issue - e.g. trying to run HD Audio passthrough in Kodi) Beta release currently but full release expected to follow soon. Can you confirm this new driver will be appropriate for the Z83-4 Graphics chipset? i.e. with this driver installed, will the Z83-4 be able to run HD Audio Passthrough?
