The short answer is if anyone in the group doesn’t want you playing it, don’t play it. Full answer:
(4) Audio and Video.
Listening to audio or watching video on matters unrelated to the competition being played (such as a news report or background music). But in doing so, consideration should be shown to others (see Rule 1.2).
Not Allowed. Listening to music or other audio to eliminate distractions or to help with swing tempo, or Viewing video showing play of the player or other players during the competition that helps the player in choosing a club, making a stroke, or deciding how to play during the round.
All players are expected to play in the spirit of the game by:
Acting with integrity – for example, by following the Rules, applying all penalties, and being honest in all aspects of play.
Showing consideration to others (IE MUSIC)– for example, by playing at a prompt pace, looking out for the safety of others, and not distracting the play of another player.
Taking good care of the course – for example, by replacing divots, smoothing bunkers, repairing ball-marks, and not causing unnecessary damage to the course.
There is no penalty under the Rules for failing to act in this way, except that the Committee may disqualify a player for acting contrary to the spirit of the game if it finds that the player has committed serious misconduct. (This will be applicable for those taking the flag out purposefully)
Penalties other than disqualification may be imposed for player misconduct only if those penalties are adopted as part of a Code of Conduct under Rule 1.2b.
b. Code of Conduct
The Committee may set its own standards of player conduct in a Code of Conduct adopted as a Local Rule.
The Code may include penalties for breach of its standards, such as a one-stroke penalty or the general penalty.
The Committee may also disqualify a player for serious misconduct in failing to meet the Code’s standards.
