Thanks for the prompt reply. My answers below:
Are you using a bluetooth speaker by chance?
No. My ipad is connected to the audio system using a cable connected through the charging/accessory port on the ipad.
Does it happen on specific songs, all songs, or just randomly?
It only happens on walkup songs (not pregame or between innings) but happens on all of the walkup songs.
Are you using Apple music songs? If so are they downloaded or streaming from the cloud?
I am using Apple Music songs which are downloaded to the ipdad.
Are you using announcements? If so, what type and are they before, after or mixed with the song when this occurs?
I do not use announcements.
Have you tried power cycling the device to reset the Apple music player service?
By power cycling, do you mean turning the ipad off and then back on? If so, yes.
