As soon as the display is off, the music is also off.

In lock screen it playing the music again.

Not so with google music, that works fine.

This happen if I connecting my phone with the music centre over hdmi and usb-c cable. I guess this is because huawei is thinking that he has a monitor pluged in and is like a PC, because of the hdmi cable. I can see also this habit with google music.
