To change di default sound device please:
Look for sound in the start menu:

and click on "sound" in the control panel section.
Then you will notice that the projector "Optoma" has a green check-mark wrongly
Please right click on "Speakers" and select "set as default device"

Just in case, Set the speakers also as default communication device.

This problem is happening frequently, maybe after reconnecting the HDMI wire when the computer is switched on
if the problem persists, also check the side button on the left of the board


the button must change from red to green for the speakers to work.
