Kevin, first of all, thank you very much for coming back to my question again. Only one last question: What do you mean by AppKit runloop modes? Are they accessible in a Catalyst environment? Thanks Markus

Thank you for your answer. [quote='807092022, DTS Engineer, /thread/764006?answerId=807092022#807092022'] So, my main advice here is to rewrite things so that you stop doing this. It might be possible to get this working (see below) [/quote] I do not find anything below you referred to. Can you please advise? Thanks and regards Markus

Same here on a M1 machine. Very annoying during development.

I finally also got voice chat to work again. The solution was to not play any other game sound while voice chat is active. In the past the game sound was muted by iOS automatically, now you have to do it yourself. If you try to play even one sound, the voice chat stops immediately. But I have one question to the guys who seems to have more voice chat experience here (by the way AirWings is pretty cool): the volume the voice chat is playing is 100%, not matter if the volume slider is at 0 or 100, and not matter if I call setVolume:0.0 or setVolume:1.0, no matter if I call this before or after I active the voice chat etc. It is really very loud. Does anybody has an idea what I'm doing wrong? Thanks a lot for any help Markus
