Airplay Apple TV A1427 discontinued?

Iv’e noticed the last days that i can’t stream audio-only from my iPhone 13 max pro to my Apple TV A1427. It works from my Macbook air m1. Iv’e tried everything possible, but nothing can get my iPhone to stream any audio except when streaming video as well. So have apple quietly just removed the audio profile for airplay 1 on iPhones with latest iOS?
