Music reset issue on playtest

[AoAGeneral]

The music will reset randomly in the game whether you are playing or spectating. It seems to be causing it when the airstrikes or other ion/nukes are being used which has those notifications missing as well.

Possibly related to #11781?

I think it is. If the change makes it so units don't constantly repeat themselves that can do it. Probably the reason why notifications aren't heard half the time with A10/Nuke much like RA.

I actually haven't checked D2K yet if that happens there too.
