I want the volume key of my phone to always change the media volume of my phone by default, not for casting devices. How to do that?
The "Use Volume keys for media" option is activated, but only to avoid changing the ring tone volume, and not for the casting. The purpose of the volume keys of my phone is to change the volume of... my phone, not another device!
If I want to change the volume of my casting device, I can open the volume centre.
