Capacitor with cordova-plugin-nativeaudio produces no audio and no errors

Using latest Ionic 6 and Capacitor 3.4 and following the instructions here: Native Audio | Cordova Native Audio Plugin for Audio Playback

Note: I am using a fresh install just to insure the plugins I need from my old Ionic4/Cordova project will still work with Capacitor. I have this same plugin installed on my older Ionic4/Cordova app which has been running for several years now.

The plugin installs and works without error however there is no sound from the device. No errors are produced either. I can preloadComplex() the audio file and no error response, all OK. I then play or loop and the response is “OK” but no sound from the device. Volume is 100% and the old app still works on same device.

JS Audio also works OK.

const audio = new Audio('assets/sounds/notification_triple_ding_loud.mp3');;

Please advise and thank you for any assistance. I am really enjoying Capacitor over Cordova.
