I have noticed that when using call apps (signal and Google meet) that when i use wired headphones the phones microphone no longer works. These headphones do not have an inbuilt microphone. This was not always the case as I've used these wired headphones during calls before without issues but it's been a while so i can't try and link this to a specific release.
For reference, the global microphone permission is enabled and both apps have individual microphone permission enabled. Any thoughts as to why the microphone isn't working?
