How do I get audio from my Ipad Pro 12.9 to come out of my P125 speakers with Ravenscroft app and Garageband app?

Hi all,
I can’t get sound to come out of my P125 speakers or PA speakers from Ravenscroft 275 app on my Ipad Pro 12.9 or from Garageband app. I used an Apple USB-C AV multiport adaptor with cable UsbA to USBB. No luck.

is the sound playing in your iPad speakers ?? if yes , go to system preferences / click
sound / look for input /output .clicking output it should have the cable you are using /click it . ?? if its not switch the sound will continue to come of your i pad & not from the cable to the speakers
