[SOLVED] Rpi allo boss dac no sound via Bluetooth

[Nutul]

Hi all,
iPhone 13pro to RPi with Allo Boss DAC. To Denon Amp. 

Can’t figure this out. Trying to play audio via Bluetooth. I can connect to it and Apple Music says it’s playing to Moode Bluetooth but no sound. 

Bluetooth renderer is on
Pairing agent is on. 

If I switch back to Airplay it plays fine. 

Any help appreciated. 
Thanks

Many times a BT-with-no-sound is just the source device's (your iPhone) volume too low.
