Several Sound-bugs because of missing sound files.
Have a look in the sound.cfg file.
There are used several sound files of the legacy FSX B737-800.
But these files doesn't exist in P3Dv2 or P3Dv3.
And that is why there is no gear up/down sound hearable as example.


The following sound files are missing in P3Dv2 and P3Dv3:

- [GEAR_UP_WARNING_SOUND]
- [STALL_WARNING]
- [EXIT_OPEN]
- [EXIT_CLOSE]
- [OVERSPEED_WARNING_SOUND]
- [AP_DISENGAGE_SOUND]
- [GLIDESLOPE_WARNING_SOUND]
- [GEAR_DOWN]
- [GEAR_UP]
