Iphone 12, IOS 15.6.1
I’ve always had the music and sound volume all the way down. In the past couple days it started playing a tune while the volume is still down. It usually only happens when I have a Bluetooth connected but it has happened out of the usual phone speakers as well. Its not the usual music. If you go into settings and increase the music volume it plays a different music.
It happens almost every time I have blutooth connected. It started about 1/25/24
You’ve entered the Twilight Zone.
fix… dump the iphone, get android 
Hello 
In order to ivnestigate this issue further, please record video footage of this volume/music issue so that the development team can see which track that is being played.
Couldn’t attach it here but here is a video I put on Twitter.
Hello
Thank you for the video!
I’ve added this into the report for the development team to take a look at.
Thank you for your patience.
Please also let me know if this issue is occuring on other platforms other than IOS.
Hello
I’ve been notified that this issue is most likely with your device as the music track that plays when the Gems of War sound volume is down does not belong to Gems of War.
Perhaps you have another app open in the background that is playing music.
It stops when I close gems. Its not from another app.
Here it is doing it again, you can see it stood and starts with gems and I’ve closed out of every other app.
