A popping sound from speakers occurs when starting up from boot. My car has an OEM amplifier (JBL). The sound scales with the car volume setting in stock settings->Amplifier settings->car volume
Setting this to >40 and rebooting the device results in the loud popping noise.
Tôi cũng bị hiện tượng này khi khởi động
Same here using an external OEM amplifier.
I'm also having this issue. And I have an OEM amp.
I also have same issue
playing with settings today I think 'power amplifier' slide control impacts the noise...mine was at like 700
picasso1850 Yes, mine is too. But this setting doesn't help. The pop sounds still happens in my case.
Has anyone here found a resolution to this yet? Feel free to only respond if you had a good outcome with a solution to share.
I'm also having this issue.
I don't think the owners will sort it out. It's up to the programmers. For example, during a reboot, the rca outputs would be muted for a few seconds.
Maybe digital outputs don't have this bug.
Still occurring on DuduOS 3.5
Happening for me in DuduOS 3.5 as well.
For posterity, this issue is partially resolved when the AMP C cable from the harness is connected to the AMP CONT cable coming from the speaker output and SIM card connector cable. If you don't have an AMP C cable exposed, connecting the AMP CONT cable to the CANbus's ACC pin will work (in my case it was Pin 9).
After that, update the MCU by extracting the files from here into the root directory of a USB drive and restart the head unit. More information can be found in this post. The speakers should no longer pop when starting the car from a shutdown but will if manually rebooting (will be fixed in a future update).
