Is there any way to turn up the volume on the Air Traffic Control. I already have the volume set to 100% on the Options - General - Sound. I have the engine sound at 20%  and Environment and cockpit at 99%. The only thing that's really loud is the engines. If it wasn't for the ATC text I wouldn't have any idea what is being said. I have seen a couple of other posts about this issue but no fixes that make any difference. Is there a sound adjustment for ATC in any of the cfg files? 

I had this problem a while ago. Turned out for me com1 was turned down for some reason.

I've had this problem come and go for the last year or so. I'm sure it was the Windows updates changing things. There have been lots of sound related changes.

Sometimes, changing the "Default format" setting under advanced options for my speakers helps me. No particular setting. I currently have it set to "32 bit 48000 Hz (Studio Quality)" after the last time it had the low volume problem.

I solved this problem by turning the engine sound down to 5% and adjusting environmental and cockpit sound to 80%, leaving the voice at 100% and cranking up the main PC volume significantly. This turned out to be a good mix. Voices are now easily heard. I just need to remember to turn down the main volume when I shut down the simulator.

And there was me, thinking it was just me. Despite a complete new,recent Windows 10 x64 Pro clean install, the sound in P3D v4.5 will, all of a sudden after half an hour just go off. Have to kickstart a website's radio player just to get the sound back. I fully concur with you, it's a Windows Updates whatever they have screwed up. And even before it is suggested, my soundcard (Realtek on-board are the latest) drivers.

It's so damned annoying, and this was supposed to be the end-all of Windows, huh/ Never had this issue raise its ugly head in Windows 7x64 Pro!😡

Maybe it's the same issue I had with RC4.

Go to Control Panel -> Hardware and Sound -> Sound -> Communications (tab): Click "Mute all other sounds" and click "Apply". Than click "Do nothing" and click Apply. Than click OK. This solved my issue with barely audible ATC.

I have the same problem and I do not even have a communication channel. I just have the default channel servicing my 5.1 Logitech hardware. Works great in every other game.

I’ve gotten into the habit of doing this before every simming session.
