Don't know if this is the place to ask, but here goes:One hour in to the flight in the 747-400 between KSFO-RJAA, my engine sound disapear from spotview and cockpit(i think) as well as my ATC sound(Radar Contact). Swtiches and wind sound is all there. Anyone had this problem? Solution?Been flying with this setup for about 6 months flawless and now this happens.Many thanks in advance.Regards/

I have had the same problem but not had a response yet - it seems to be when you go from cockpit to spot view.

Nick,I had a similar problem and I think(it's been a while) re-installing my sound card driver seem to fix it. Hope that helps

My ATC just gets distorted, but pause/unpause fixes that immediately.I think I had the problem before I got the -400X.Possibly started after installing another addon...Cheers,Greg Smith
