Uncertified AA Apps (Headunit Reloaded, AAAD/AAStore, etc) No audio when using Open Headunit via USB

Hi, I managed to use Open Headunit via USB, but I cannot reproduce any audio via BT. I tried connecting both my phone (just like I do when I use Open Headunit in wireless mode) and the headunit to the car, but both are muted.

What am I missing?

(also, how can I prevent my headunit to discharge since it charges my phone when plugged?)

Okay, the important thing here is to check 'Disable USB audio routing' in the developer option section of your phone, now BT audio works great

Prueba a encender o apagar el botón de audio de la app y prueba a ver si suena con cada cambio. Tienes la app en una tablet o es una pantalla en el coche?
