The Latest Drivers I have installed is the 19.11.1.1 (Nov 2019), the HDMI audio works fine with this driver.
Drivers released after that date have an issue with sound. I have no sound from the HDMI Audio which is connected to my TV. I've tried the latest Nov 2020 driver and the issue is the same. What can cause this and is there a way of getting the HDMI audio driver separately from the GPU driver installation.
