Noted this too in a user-made mission with a static MI-26 the helicopter was buried into the ground. Also this is the wrong place to report mission editor bugs.

Make sure you are installing as administrator. If that does not work I suggest you re-download the file as it may have not been transferred in full.

I've been having the same issue and it seems to only take affect at higher altitudes and only from my left set of speakers (5.1). I have onboard audio on an Asus M4A89GTD PRO. When I get up to altitude it will start to make the crunching/crackling noise from left speakers with distorted audio only from those speakers and then cleans itself up after 10-20 seconds. Unlike you I have only had this issue since upgrading to Beta 3. The last time I had it happen after leaving the game none of my audio seemed to work besides teamspeak 3. Running the 32-bit executable in Windows 7 64-bit.

You can go to map mode ( F8 ) while in game and click on the airport icon to bring up the tool tip pertaining to that airport.
