Yes, but it's configurable on the Options #1 page. The idea is, if you're using TGS in audio mode, to make ATC quieter so you can hear the PNF telling which way to turn. I think it defaults to a 25% reduction but as I say, that's configurable to your liking
Hey Dave,
Actullay, that was not what I meant. I meant that the interaction with AI traffic stops. I stop hearing ATC giving clearance to taxi runway or to gate to the AI traffic. And that only happens after landing and switching to ground. I still get runway crossing instructions though. I stoopped using tgs audio after installing tgs gauge.
