BMW Speaker Beeping

This faint beeping noise was coming from the dashboard area of my 2021 M440i. I finally traced it to the dashboard speaker. If you plan to unplug your speaker, I recommend just taking out the 3 screws holding the midrange speaker in place and unplugging it, instead of removing the bracket that holds both speakers. The bracket was glued at each of the 4 screws and was hard to remove.
