Sound problem?
 

Is this a 4.10 bug as I cannot see any mention in the 'Bugs' thread but has anyone noticed the following problem. (Clean 4.10 stock)

If during a mission (with realistic Nav) the beacon is switched to 'none' or not tuned in to e.g, Radio Honolulu and then exit the mission all music sound tracks are disabled. It seems you must select a 'radio' beacon before you exit.
