Hi everybody. I'm not sure if this is the correct forum section so i apologize in advance if I'm mistaking.
i'm trying to send audio from a digital device/bluetooth receiver to a Raspberry Pi's audio input through cable (Rpi's bluetooth device is unusable).
As soon as i plug the 2 devices togheter with the cable, the bluetooth device completely switches off.
IF i connect them BUT i keep the Ground of the audio signal unconnected, then all is working. Why and how could i solve this?
Both of this 2 devices are powered from the very same power supply that provide enough current but also when they were powered separately, i had the same issue
I will upload a drawing to be more clear.
