MacOS - dock182euz Audio over HDMI Port(s)

Hi,

Targus dock182euz
MacBook Air M3, Sequoia 15.3.1
USB-C connection MacBook to dock
2 Samsung 1080p monitors on dock HDMI ports

Is audio over HDMI supported?

In MacOS SystemSettings/Sound there is an option for <Targus Audio> <USB> but this seems to be output to only the analogue sound port on the dock or the USB C front panel port on the dock. (Obviously the USB C output needs a USB C -> 3.5mm analogue cable with built in DAC). Sadly both these options seem to pick up interference, there is a 50hz low level buzz present (I'm in the UK).

I used the same displays on a Microsoft Surface with the Microsoft Dock, same cables. Audio was crystal clear

Am I missing something?

Thx in advance
