Whe fire stick is in projector and playing the audio is not syncing thus talking is delayed.how to solvevthe problem

Solution
If the sound is coming from a speaker inside the projector than check the projector menu to see if there is a way to adjust the sync
If the sound is coming from a separate audio system or soundbar then check that for lip sync adjustment. You may need to connect the Firestick to an HDMI input on the audio system and use the HDMI out of it to connect to the projector.
Last option is to check the Firestick audio menu.
