I have installed the latest OS version 3.6 E and the latest Bluetooth version on the Dudu 7. Unfortunately, I have the problem that no sound is coming through the speakers during a phone call. Since I want to connect an amplifier via the RCA for the front speakers, I have not installed and connected it yet for test purposes. The rear speakers are producing all sounds normally. As soon as I want to make a phone call via Bluetooth, the sound should also be output from the rear speakers, or is it possible that the sound for phone calls is only output from the front speakers? I have set the setting on the DUDU7 to Other. I can be understood during a phone call, but I cannot hear anything myself. Or could there be something else wrong?
