(not English...)

Hi !
I've got a problem on Spotify desktop applicaition.
When I connect the bluetooth speaker ( Philips SBT300/12 ) spotify speed up the song x2 so... 1 sec = 2 sec of the song....

When i switch off the Blt speaker and plug ears speakers  the rythme slow down to normal speed 1 sec = 1 sec....

Don't know why first time i see that and just on spotify.
(i m trying the *free period* premium).

Thank you for yout reply.
