Controller + Bluetooth speakers

Hello, please I need your help.
I have connected my Ipad via Bluetooth with my Samsung soundbar. This works perfectly (yes, there is latency, but it works for me).
The problem is when I connect my Denon MC6000 MK2 controller. The mapping works perfect, but I can’t get the sound to come out of the soundbar. please help, thank you

Please check in the settings of the app if the audio output is set to “iPad speaker”.
