We have an app using CallKit since it's been introduced and had to deal with different kind of CallKit bugs and/or behaviour changes after almost every new major iOS release. But we have no ideas what to do with issue we observing on iOS17. Some users report no audio on first OUTGOING call only after app started. Subsequent calls have audio. Logs showing everything is fine - Audio Category is set, AudioUnits did setup, CallKit did activate AudioSession, and app is transferring audio frames to/from AudioUnits. But no audio. We've got reproduced this on one of devices we have and was able to fix the issue by removing paired Hearing Aid configured on the device (however the Hearing Aid was never used with this device, just config for it was iCloud synced). But we don't have confirmation from other users that there is a dependency on Hearing Aid device paired.
Did anyone hit this issue as well? Any suggestions than fill Bug Report that most likely will sit forever with Apple?
