Thanks, when the options "transient" and "transient-solo" are selected, the audio from the web app is now mixed with the audio coming from the Music App on iOS, but on MacOS Sonoma 14.4 the audio from the web app is always mixed with the audio from other apps, regardless to what navigator.audioSession.type is set to.

When navigator.audioSession.type is set to "play-and-record" on iOS 17.4 it still pauses the audio from other apps when the mic is accessed from the web app with navigator.mediaDevices.getUserMedia.
