GSX Pro No Sound **UPDATE**

I covered this in the last part of my reply:

Another possible issue is windows lowering down the volume for out of focus app automatically, but there's a setting in Windows to prevent doing this.

A GSX log might be useful.

As mentioned my lack of GSX sound is intermittent.  Today it did not work.  Log file attached in case this can shed any light.

Thanks

Exactly what you said for some reason Windows is turning my speakers off for GSX, I downloaded a program called EarTrumpet which gives you the ability to raise or lower the volume of all apps that are running. The program can be found in the Microsoft Store, Umberto, thanks again for all of your help, I now have sound coming back out of my speakers for GSX!

For the benefit of Others..  I may have found the problem, although I do not know why  this has become a problem.
As previously and helpfully suggested I downloaded that Ear Trumpet software and checked the levels of running Apps.  In my case there was NO Couatl entry in Ear Trumpet so naturally no sound from GSX, I restarted Couatl and the icon appeared and I had sounds. 

It appears that in my case when starting Prosim Audio, it stomps on and replaces the Coautl sounds module.  As soon as I start Prosim Audio I watch the Couatl icon disappear from the Ear Trumpet app and all my GSX sound go away..  Generally Prosim and its modules are always started after FS2020 has fully loaded. The reason for it being intermittent is probably because I have started Prosim prior to loading the flight without realising it and on those few occasions it has worked correctly.

I do not know why this happens/ has started happening but now I know I can get round it.  If anyone has any input before I ask the question of Prosim please do comment.

I am running MSFS2024 not sure if that has anything to do with it but I have Ear Trumpet running all the time. Once I loaded the simulator and started a flight, I went to the taskbar clicked on Ear Trumpet expanded it and noticed that the slider for GSX was all the way to the left I moved it to the right and had full sound. Is prosim a stand alone app for MSFS2020? It should show up in Ear Trumpet if you expand it

Prosim is an entirely seperate Avionics module that works with MSFS in my case over the network.  The Audio Module shows separately in Ear Trumpet.
What I was saying was:

When MSFS starts GSX/Coautl starts with it (Thats correct) If I open up EarTrumpet it shows the Couatl icon correctly and working.
If I start the Prosim Audio Module after the flight has loaded then it stomps on the GSX/coautl audio module and that disappears from ear trumpet (GSX still works but without sound)

Prosim has to be started after MSFS so that it can see it on startup.  The work around is to Open Prosim and its modules after MSFS has loaded but prior to clicking "Fly Now"   Failing that right clicking on Coautl and restarting it also works.
