I work at RNR. When that happens, it's because a disabled person is loading into the third row of the vehicle at unload. Launches are automatically inhibited until the guests are completely secure. This has unfortunately taken like... 8 min to do, depending on how slow they are. Spotty audio occurs due to the launched car being away from a station for too long, and is hard to do anything about. Remember, vehicles are charged at unload and load; do not have their own power sources, and begin discharging immediately after leaving the charger.
But right before the Refurb in September, they are upgrading audio to another system, which should be tested this week sometime on vehicle number 3. The refurb is going to be on electrical and launch base control systems, and is 100% needed and planned for at least a year. The Jan refurb was the addition of the single rider line and replacement of magnets along the LSM.
Hope that answers your questions.
