2 slow beeps when media is playing?

[Holycal]

When media is playing and the phone is in loud mode, there's this constant 2 beep sound. 

When it's in vibrate it vibrates twice.

What is this and how do I turn it off?

It's not notifications. Only happens when media is playing sound.

@Holycal  did you try the same in safe mode? You should be able to play some media and see if there occurs the same behaviour.

Hi there, you can do the speakers test from the support app on your device and check if you will hear the same thing or not.You can also try the safe mode as it will disable all the functions of all the 3rd party apps on the phone so you can know if it's caused by one of them or not.
