Issues with ATC

I’m having some issues with ATC it starts off fine guiding me well then about 3/4 away into the flight stops working the AI will confirm what ATC is saying e.g. height reduction direction but I don’t hear it this is especially problematical when you’re coming into land using IRS is it just a problem I’m having even though this is only recently happened after the last update or is it something that I’m doing wrong.

Step one would be to make sure the volume knob on the radio is set to max

Volume on my pc Doesn’t change from the start the flight to the end of the flight

Not on your PC, on the actual radio in the cockpit in the sim.

No, this is a very well known bug.
There a lots of posts here on it.

See this thread.
