I noticed that the marker sounds do not come on anymore.

 

Any idea where I should look to get this fixed?

 

I do get the lights come on for these markers

Which aircraft, sometimes there is a switch to turn the marker sounds on and off on the radio stack. 

Almost all aircrafts I have this issue.

I have the Go flight module buttons where I do turn the marker beacon and Nav sounds on

I see this problem in almost alll PMDG aircrafts, the CS 727.

 

 

 

Did you get this sorted Manny...?
