Radio device music cuts when many other sounds are played simultaneously

Summary

Background music (played via a Radio Device) cuts out completely when multiple players are simultaneously driving vehicles nearby, and resumes once fewer vehicles are active or they move farther away. This appears to be a recurrence of the previously reported issue FORT-747352 (“No audio when there are too many vehicles in the same place”), which was marked “Fixed” in May 2024, but the same symptom is still reproducible.

Steps to Reproduce

Place a Radio Device playing background music.
Have multiple players (5+) simultaneously drive dirtbikes near each other.
Listen to the background music while several vehicle engines are active nearby.

Expected Result

The background music should continue playing normally alongside the vehicle sounds.

Observed Result

The background music cuts out completely while multiple vehicle engine sounds are active nearby. It resumes once the vehicles are farther apart or fewer are active. Only vehicle sounds remain audible during the cutout — matching the exact symptom originally described in FORT-747352.

Additional Notes

This looks like a recurrence of, or an issue closely related to, FORT-747352.
Playing the island given in the Island Code section with many players at the same time will trigger the bug, as dirtbikes and ambient music are both involved in the core gameplay.
