iMiX16 apps for iPadOS - Audio via headphones jack, video via HDMI

It turns out if you first connect HDMI to the iPad and then launch the iMiX16 app and lastly connect the headphones jack, the iPad routes the the sound via the headphones jack and not the HDMI cable. This was tested on iPadOS 13.2.2.

Thanks to user Henk G. who send us this solution.
