For awhile it was working just fine… Then as of yesterday when I had an update the ATC now loses sound during the flight if I have my copilot responding… I noticed when I removed my navigraph data the ATC did not lose sound… Does anyone know what is actually causing this?

Whenever client demand for Azure ATC voice/text exceeds supply, one side of the conversation will be lost, whether it is AI co-pilot or using 2 radios to listen to ground and tower at the same time

Yeah this guy’s right (as are others who noted the traffic congestion is a leading correlation).
After nearly 28 flights since the patch (and nearly 100 since SU9), the pattern is clear. It almost always happens when I transit New York, Washington, Oakland, or Los Angles ATRCCs. Sometimes in Chicago, Boston, or Atlanta. Almost never happens around other, less busy centers like Denver, Kansas City, Houston, Ft Worth, Mexico, Canada, or most of Europe. I’ve also noticed that peak hours are worse than non-peak.
I have noticed a possible solution if you want to call it that… So if I turn the ATC over to the co-pilot after I have been cleared to my cruise altitude it will work the rest of the flight… I have tested it a few times as well as a buddy of mine and it worked like that each time…

That sounds like a workaround I could live with. I’ll give it a go! 
So it stopped working even with that but I was able to get it back… I am using the FBW A320 so I switched the ATC to COMM 2 in the ATC window… Then in the plane I switched to VHF 2. and it worked…
However I also went into my assistance settings in MSFS and completely turned off the AI controlling comm setting that way I manually have to assign it every flight and it worked from take off to landing for my 2 hour flight.

Well, so far, this is the best I’ve been able to do. I left KBOS en route to KATL, and passed through NY & Washington ARTCCs with no loss thus far. I’ve never been able to pull that off. Small price to pay if it works even 50% of the time!
I have a problem with the ATC sound. If I use loudspeakers I only hear the sounds of engines, switches, environment, but not ATC orders. With the headphones if I hear the ATC. I have tested the speakers with other programs and they work fine. Sometimes the ATC sounds through the speakers, but other times it doesn’t and I don’t see the reason. Does anyone know why it could be?
Especially if you have USB headphones or use the loudspeakers using an optical connection (SPDIF) check that you assign something else than “default device” in your sound settings.
In MSFS you have two settings to do so, one is for communication, the other for sounds. Set both to your soundcards loudspeaker device and you should be fine normally.
FWIW I’ve just this happened (yet again) whilst using the Cessna 414AW and the TDS GTN750xi, although it has happened with different aircraft types in the past.
I found that moving all the comms onto box 2 seemed to fix the problem and get the ATC voices back.
I just do the comms myself, and have never lost ATC. It’s a shame that I can’t hand comms to copilot, but at least I never lose comms. Hopefully it’ll be fixed in a few years…

my solution is that I shut down the game after each flight and restart if I want to fly again.
It is a bit troublesome because I have to wait for the game to reload but it really only takes about a couple of minutes.
I don’t turn on my co-pilot until I am ready for the pushback. So far my ATC has always been heard. It did go silent when I first played back to back flights. On my 2nd flight I was nearing to land and my ATC when silent but my co-pilot was still calling out the read backs so I did know what to do.

Brief description of the issue:
Sound cuts out from ATC using payware aircraft. there is something wrong with how MSFS prioritizes its sounds. If i use the PMDG or Fenix payware aircraft, the ATC sound cuts out of sim. you can no longer here the sound but only read the text speech in the atc menu. what i was told was this…there’s no fix for the sound cutting out, it’s due to sound priorities that MSFS puts on the package as a whole. The user aircraft (payware) requrires its sounds, the ai traffic (AIG or FSLTL) require its sounds. MSFS has something imbedded where it has reached its max capability. Something needs to be fixed on the MSFS site.

Thank you! This solution is the only one that workec! Highly appreciated!
I have it too but not always. Sometimes ATC sound get lost short after take off and wont come back. I did not changed any settings and I tested if the sound was muted in cockpit but it was not. Extremely annoying and it completely destroys the immersion.
No that is not the problem. I did this way and the sound disappears nevertheless very often.
I guess you are right. Asobo knows, but they are not able to fix it or probably not willing. Anyway, it is completely frustrating and destroys the immersion.

Just make any flight and about 30 minutes into it, the ATC loses its voice. I still get text messages but need to watch for them. Only a game restart fixes it.

ATC Sound cut off after a while– Just updated to the latest update released in December 2023 - (Thanks for some ATC fixes). I am using flybywire A-32N and Fsltl traffic injector and have a navigraph subscription with sim link to iPad. No add on liveries.
When I start a flight and I have the usual ATC clearance…. I fly for a while on the climb out, up to cruise then lose ATC sound – especially in busy area (lots of FSLTL injected traffic). When it happens, I switch to VHF number 2 or 3 (with max volume) and wait for a while with only the ATC text appearing.
Potential Solution - I wrote “Potential”
Most of the time, ATC Sound will come back after ATC switches me to another control sector/area frequency, (if I remain on VHF 2 or 3).
It happens with flybywire, MSFS B-787, 747 and PMDG 737-800 and 900 (now removes). The only common issue is that I use Navigraph on all of those planes and FSLTL injector with limited to 30 traffic at the time in a 90 miles range - no VFR. It’s really annoying.
Some mentioned above that it may be related to (Azure server) (I am using Full high speed unlimited Fibe internet) – any idea how to test that or reproduce that with specific tool to troubleshoot this so called “perpetual ongoing ATC issue?”
It the mean time, hope this “potential” solution could help.
