Hello Guys,

after a few weeks I wanted to fly the 767 again when I found out that when I pushed the switches and buttons in the cockpit, no sounds could be heard. I only hear the engine noises and flap noises anymore! What is that supposed to mean? I've already read my way through countless forums and tried the tips, but none of them worked. I also did a new installation 3 times and restarted my laptop several times. I am very surprised that the problem suddenly appeared.

Can someone help me?

Thanks in advance.
