Broken Alarm Clock with Bluetooth Headphones

[hans_g]

Hello

I discovered an error with the build in iOS alarm clock app. It will play no sound when the Spotify app is open in background. 

Steps to reproduce:

Listen to music with Bose QC35 II Bluetooth Headphones -> Start a call over the headphones -> end call and resume music playback -> in background the alarm is already activated for the next day -> stop music playback -> go to sleep -> be late because alarm is silent
