Radon 4200 HDMI audio failed to install

I installed updated driver for Radon 4200 the audio interface for HDMI failed to install twice.

turn off the antivirus and firewall FIRST.
If there are multiple security programs installed, they ALL must be shut OFF first.

After installing, open the Video card software. You have to turn the HDMI audio to: ON,
which will disable other audio outputs. You can only use ONE audio output at a time. For example, HDMI audio OR speaker output from computer, BUT not both at the same time.
