Projector wireless speakers

Solution
Make sure that the projector audio output works with the HDMI input of the projector. Some don't.Then connect a bluetooth transmitter to it. Pair the speakers with that.
If not then you will need to get audio from your sources. An HDMI input selector with audio extraction will provide that output for the BT transmitter.
