  • Exploring the problem of popping sounds

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

          VishBK Video providing version information and popping sound

              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.

                                  1. Original Car Manufacturer AMP (Alpine)
                                  2. AMP control wire not connected

                                  Side topic but may be associated? - The dudu7 FAN is always running in Auto mode regardless of configured TEMP setting. The only way to stop fan from operating is to select OFF in Fan settings.

                                    dudu-lai Amazing! Initial test worked, fan shut off immediately. I will test TEMP control over the next couple days when driving.

                                    I also didn't hear the popping sound during initial test and I think sound balance across APPs appears to be functioning again....I will update this post later this week to confirm. Thank you so much!

                                      No more popping sounds and temp control of fan is working flawlessly. Thank you for starting this thread and resolving the problem for me @dudu-lai

                                      dudu-lai it's still popping after the update, (allpine amp).

                                          same here still popping on harman kardon amp - subaru outback. the one million dollar question is does this software update also requires connecting the amp cont cable (2) to the amp c harness cable to work? which means i have to take the dashboard apart again?
                                          I updated just the software , i never connected those cables during my initial installation because i was never instructed to do so. which should be from the get go clearly stated. this is not my first android head unit on the subaru with the exact same amp, and same harness since i am using the same canbux simple tech one for my subaru. can anyone confirm this fix requires the hard wiring posted on the top of this post. thanks for everyone feedback.
