I have set up the NUC as an HTPC. The HDMI connection from the NUC goes to a receiver and then from the receiver to the TV. The PC desktop is displayed on the TV but no sound output devices are found. The PC says that nothing is connected?
I have checked the HDMI cables and they are working. Reconnected my old NUC6i7KYK and is able to send audio and video through receiver to TV.
I bypassed the receiver and connected HDMI directly to NUC. Video and sound were sent to TV.
Why would the NUC HVK HDMI sound not work when connected to receiver?
