Hi all. I just joined the forum and am a month into FS2020, having migrated from FSX. Just wanted to say I’m having ATC sound problem also, but happy to learn it’s not something I did. 2020 is hard enough to adapt to without mystery problems popping up (tks to all who post YouTube vids, I’d be completely lost without them). I’m pretty sure this problem happened to me after I installed several country updates.
Hope to learn a lot here, and hope to be able to contribute in the future.
