Hi Steve, are you specifically seeing this happen in Mobile Safari? There’s a bug right now in iOS15 causing audio to be routed to the earpiece instead of the device speaker. https://bugs.webkit.org/show_bug.cgi?id=230902

I think someone who tried this with a web version I had built from a very slightly modified version of the client-js example had the same issue on android. Bluetooth wasn't an option for the audio output. I think he then tried building the flutter app and had issues with it there too but managed to make some changes to get it working. Sorry, I don't have more details since it was just some quick testing that we haven't followed up on yet.

@magnificent-art-43333 on IOS 15 Safari & Chrome. But YouTube on browser is louad and also push to bluetooth speaker OK...

AFAIK, YouTube isn't using WebRTC for their audio playback.

here is a little trick to get around the bug, instead of putting the whole stream into an video element, grab both video and audio tracks, then put the video into the video element, then create a audioContext for the audio, then your speaker will work
