Deezer volume goes to 50% when connected to car bluetooth

Hello ​@Dadoooor apologies for the late response.
Is this problem still happening?
Do you use Android Auto or Car Play in your car?
Thanks

Hello, yes, it’s still happening.

I don’t use either AA or CP, just plain old Bluetooth ;).

To better understand the volume decreases in your car speakers?
Thanks

Yes, that’s correct. 

Could you please check if you have the “normalise audio” option activated in your Deezer app?
 

Hi, it’s not activated.

This is a problem I also have. Whenever I connect either an iPhone or an iPad to a bluetooth speaker of any kind the bluetooth volume is always reset to 50% (in Deezer).

Same here. Glad to hear I’m not the only one.
