Hi I came across a suspicious icon on my screen and I'm wondering what exactly it is
This periodically would automatically appear on my stream while I was streaming on Twitch, without me pressing anything. It seems to be some sort of speaker icon?
I believe that you are paired to external speakers and that icon will appear anytime that your volume is changed. Specifically if you hit the volume up or down while connected to speakers. Could also appear if speakers have their own volume control, in which case the icon will appear on your paired phone whenever someone adjusts the volume.
You should be able to see how your audio is being routed from control center.
Hope that helps. Good luck.
