  • No sound output

I have no sound output from anything optical or rca. Was working fine now nothing.
I have DUDU7 running 3.5 OS.

I just did a factory reset and still no sound output

Is there no sound when the main unit is pushed directly into the speakers?

    DUDU-Meng correct, no sound output of any kind

    No sound after upgrading the system?
    Or is it caused by setting up some program?

      DUDU-Meng sound was working, I turned my truck off and when I turned it back on I had no sound so fitted different outputs and nothing

      Then decided to do a factory reset and still no sound

      I have unplugged the unit for the night and I will plug it back in in the morning to see if anything changes but I doubt it will help

      Solved! Not sure what happened. I took the head unit all the way out of my truck, inspected all conditions and pins. Installed and no sound, did 2nd factory reset and now have sound

      It's been resolved, right?

        DUDU-Meng yes
