For a little while now, I would not hear other’s atc voice unless they had the same voice as I had and have seen here on the community others have had the same issue. I just found a fix for it; change the default voice for other pilots and ATC at the bottom of the live section in settings! I switched mine from English UK #1 and now it works!
