Problem with sound of first song

[Fr4nk79]

Hi,

I'm Using AA with a Vernee Thor (Marshmallow) with a Kenwood DDX9716BTS as Headunit.
When i connect the Smartphone with the Headunit and start Music on the Radio the sound from the song goes over the Smartphone, note the Speakers of the car.
When i skip to another song the sound comes normal from the car.
Everytime after i connect the Smartphone new to the car the first song goes over the Smartphone.
The Problem is the same with Spotify and Google Music.
Is this just a problem for me or have others also this problem?

Regards
Frank
