  • Exploring the problem of popping sounds

MihaiFlorin This car doesn't have the factory AMP, the radio is connected directly to the speakers and shouldn't pop.

    MihaiFlorin You cannot manually click restart in the radio to test.
    If you turn off/start the car normally, does it make a “popping” sound under normal use?

        dudu-lai No. But I have this "pop" sound when I reboot the unit.

            MihaiFlorin Same here.

                JhonnyD Use the reboot on the top slide bar, no popping sound

                    dudu-lai We both know about this. And to use reboot from the top slide bar is not a solution, is just a workaround. But this problem with the popping sound on reboot must be solved. I didn't have this popping sound on reboot until the last update. DUDU team must do something about this.

                        So ist es. In dem einen Update ist es vorhanden, in dem nächsten ist es weg, dann wieder da.
                        Und ich lasse mir ungern sagen, dass es an mir oder meiner Hardware liegt, wenn ich weiß, dass es nicht so ist.
                        Vielleicht finden wir ja noch heraus woran es liegt.

                        I am also having this problem on my 2017 Prius JBL with a HiWorld Canbus.

                          MihaiFlorin These two restarts are different and will be optimized at a later date

                                I just bought a anti pop sound circuit board with delay timer to try if it can help.
                                It is so loud, that i am afraid that the subwoofer could break.
                                It also comes from the speakers but it not so loud.
                                Therefore i will try that device until it is found what causes some head units to pop.
                                In normal use everything is fine, but after some days the head unit turns off,and then you can't do anything about it. In normal use you can choose how to reboot but not when the head unit is completely off.

                                        VishBK Does the radio make a “crackling” sound when I turn it on after turning off and restarting the car?
                                        The “crackling” sound when manually restarting the radio will be addressed in the future
                                        I replied to MihaiFlorin in the above message about this issue

                                            dudu-lai It's not a crackling sound, it's a loud pop (you can hear at the end of the video) whenever the head unit starts up, whether it's manual or restarting the car.

                                                VishBK Maybe there's a problem with the translation, I also meant thumping or popping.
                                                I need you to record a video of the car making a thumping sound when you start it and send it to an engineer. Instead of manually restarting it in the mainframe

                                                    @dudu-lai - Popping sound every time car starts.
