Did you add the Beam using the app?  You can't just connect via HDMI-ARC, you need to add it to the system also. 

Sometimes, you have to turn on ARC/eARC on the creating device. Have you done so in the settings on this projector?

Solution - Thanks went in to Audio on projector and it allowed me to select SPDIF/e-ARC setting which solved problem as although detecting speaker was resetting as soon as any other input eg ps5 was plugged in.
