Sounds and music to chanel

can anyone advise me on how to get audio or music to a channel I feel stupid :). When I want to play some audio, it’s only when I put it as a play sound or music.
It often happens that the player does not play in Gdevelop. After exporting to the win exe he is already playing.

Thank you all.

hi there is a bug in preview. If you do a preview of a scene which is not the main one there is no sound. So if you hace a main scene do preview from there and then go to the scene you want.
To play sound ina Channel simply specify the channel in the play action
