In my web app, an MP3 is playing through the speaker. When I call getUserMedia() API to capture audio, the audio will correctly switcher to the earpiece — which is expected. However, after releasing the MediaStream(stop the audio track), this MP3 continues to play through the earpiece instead of switching back to the speaker. Here is the Reproduction Link: https://bug.qer.im/ios-getUserMedia-cause-audio-wrong-output/index.html
