Facebook livestream audio volume changing

[Jeikobu]

My church has been live-streaming every Sunday, and I’ve noticed the audio volume has been automatically getting louder and quieter off and on. Here’s our service last Sunday where this continued to happen. It’s really distracting. I can’t find anything on the web about this. It used to be ok, but lately this problem’s been occurring. I can’t think of anything that’s changed. We haven’t changed the position of the cell phone we used to stream to Facebook. Furthermore, we also stream with a phone to YouTube, and the YouTube audio has been fine, which makes me wonder if it’s a Facebook issue. Not long ago we got a new boosting speaker, the photo of which I’m uploading, but I don’t think we had audio problems right off with that. Anyway, any help would be appreciated. 👌
