Thanks for the reply. You are correct, when you said I want to keep the table audio empty. I only want the DMD video/audio playing during the choosing of the tables menu. It probably sounds odd wanting to play a video/audio through the DMD, but my DMD is a 10" lcd screen and not a narrow standard DMD size. Hoping for new pins to be emulated someday that utilize the larger screen DMDs like the new Star Wars or Batman 66. (I know, wishful thinking)
example: Tron Legacy table, I added a DMD Video (trailer) from the Tron Legacy movie and wish for the video and audio to play in the DMD during that time. The back glass and table will only be a static image or a silent video. Basically, this will allow me to make custom DMD videos with audio as the attract mode during table selection. I hope my explanation makes sense.
I did test with no other videos running and still no audio from the DMD video playing.
