Tested with Airpods and wired headsets Here are the repro steps: * Attach an external microphone to your iOS device * In iOS Safari hit the following URL: https://webrtc.github.io/samples/src/content/devices/input-output/ * Notice that the echo you hear is coming from the external microphone (as expected) * Change the selected "Audio Input Source" to "iPhone Microphone" (or "iPad Microphone" if using an iPad) * Notice that the sound is still coming from the external microphone. I would expect the internal microphone to be used at this point. I've duplicated using iPhone mini (MG8F3LL/A) on iOS 15.1 with Airpods. I have also duplicated on iPad Pro (MLMP2LL/A) on iOS 15.2 Beta 3 using a wired headset. 1821010 1 webkit-bug-importer 2021-12-07 06:12:21 -0800 <rdar://problem/86153529>
