GSX no boarding sound

[Driver170]

At GCFV gate 20 the staircase has been disabled. So the boarding should commence with both cargo doors opened at L1 door open as i’m using an airbridge or airstairs.

The cargo men load the suitcases on but i don’t get the boarding sounds “unless” i open L2 door? But surely if i have the option ticked without staircase i should get the boarding sounds.

Using P3D V4 and Prosim 737

You should hear the sound if you open the preferred exit.

I’am using another sound package?
