You can also use a microphone to output the sound through the projector speaker.
Once connected, the audio can...

Connection 20•  You might get feedback noise from the microphone when you are too close to the 
speaker of the projector. Move the microphone away from the speaker of the projector. 
The greater volume you require, the greater distance you need to be away from the 
speaker to prevent the noise.
