Bug description

On an iPhone 13 there seems to be overactive background noise suppression/cancellation on the speaking voice to the receiver. I am re-creating this report since it was closed by stale bot https://github.com/signalapp/Signal-iOS/issues/5452

Steps to reproduce

Make a call from an Android to the iPhone, the iPhone needs to be on speaker phone mode, the Android can be speaker or headset, it does not matter
If the iPhone user switches to a headset then their audio will sound perfect to the Android user
OR, if the Android user mutes their microphone then the iPhone user on speakerphone will also have perfect audio when they speak.

Actual result: iPhone microphone is getting actively noise cancelled and voice gets cut off. This happens anytime audio comes through.

Expected result: Voice doesn't get cut off.

Device: iPhone 13

Link to debug log

I have a Pixel 7, the recipient has an iPhone 13 (brand new). When they talk (on speaker) their microphone constantly gets cancelled. I have to ask them to repeat a lot. Once they put in their Airpods we don't see any issues.

This might actually be a bug on the iPhone 13 in general. I've noticed it on normal calls too.

I've fixed this when it comes to normal calls, but Signal still seems a bit sensitive.
