Save the .ini file on your desktop then drag it back into the Captain Sim folder and select overwrite. I'm also having a few sound issues;

- 1,000 to go callout doesnt work
- Passenger sign alarms don't work in 2D panel (works in the VC).
- TCAS system test works but is extremely delayed in 2D panel (works in the VC instantly).
- Glide-slope warning doesn't seem to want to play correctly, it will play even if I am in the glide-slope.

I have the setting to "0" in the init file... I have also tried "1".
