All sounds are cut while tow truck is connected to the aircraft

[simland]

Since about 2 months, I have the following issue for preparing for pushback and startup the engines:
- Everything is working well (all sounds from the aircraft, ext. sounds, wing-walker, etc...)
- At the moment when tow-truck connects to the aircraft, all sounds are cut (aircraft sounds, cockpit sounds, wing-walker commands, ext. sounds, etc...)
- No sounds at all while the pushback
- At the moment when the tow-truck disconnects, all sounds are working fine again
Thiss issue is not airport specific; it happens at all airports.

My setup:
- Win64 Pro 64 bit, latest update
- P3D v4.5
- ProSim v 1.67 (latest update)
- Active Sky for P3D v4
- AivlaSoft v2.3 (latest update)
- GSX and GSX Level 2 Extension, regurarly updated once a week with FDS Installer or FDS Live Update

Can you help?

I have the exact same problem.

However, I'm on P3d V6.1 with the new Active Sky and Win11.

All Sound is turned off just before being asked to release parking brakes.

Comes back on after engine start and I reset the parking brake.
