Both Audio and Video on Passenger Princess Screen

[NDanecker]

Mrs. was excited to try out her passenger princess screen but quickly got frustrated as we couldn't get the audio to play through truck speakers while playing video on HDMI input of her screen. Video was not the issue - audio was. After some research it appears Ram will not allow audio through truck speakers, and passenger must use external headphones (bluetooth). Is there any workaround to get this to work????
