The "Audio" track randomly plays during attract

[lancerguy]

I have an odd issue.  My Pinup Popper randomly plays the "audio" track from tables in attract mode.  I have my cab set up to cycle through tables every few minutes.  Every once and a while the pincab will just play the 'audio' track that is selected for a table in the Media menu.  It doesn't even happen every day, and it's definitely not the same table or the same time each day so I can't chalk it up to anything specific.  It's not a major deal because it's just once a day and I don't have it turned up very loud but I'm just super curious how to pinpoint the problem.
