device.ringAsync() rings in silence and leaves the headphone in a ringing state

[emolr]

Problem:
I've been debugging the missing sound on Jabra evolve 75 when calling ringAsync(), the busylight blinks as excpected.

If I turn off the headphones without calling unringAsync() beforehand, the headphones turn on and starts playing a ringtone that can only be stopped by connecting to the computer and call unringAsync().

Expected behaviour:
Calling ringAsync() would start the busylight on the side, and the ringtone would start playing in the headphones.
Turning the headphones off would reset the state of the headphones.

Ive testet with the demoapp in this repository and it produces the same behavior
