The maximum number of sounds on the map - 200

[CCCP84]

I made a discovery that the maximum number of sounds on the map is 200. When this number was reached, I lost the sound of loading units into vehicles. With 199 sounds, the loading sound appears, but is played every 2nd loading.
I haven't tested it, but most likely, if the number of sounds is more than 200, only 200 can be played.
