Cracking sound in audio channel Acer Aspire 5 A514-53-3970

Every since I have my laptop (Acer Aspire 5 A514-53-3970 - Windows 10 /11) I have a cracking sound through the speakers when there is no music playing. It can be silent then for a while again until it gives a sudden crack again, like it was disconnected from power.

Does anyone know how to fix this?

Does this only happen plugged in? If you don't know, unplug the charger to find out if it still happens.

I tried to plug and unplug the charger, but it doesn't matter.

(1) How often do you hear the crack plugged in? Once per minute? Once per hour? Once per day?

(2) How often do you hear the crack unplugged? Once per minute? Once per hour? Once per day?

1) & 2) same frequency. So when there is sound playing there is no crack. But there is no music playing it comes back every 10 min or so (including start up and shut down). I tried to discover a pattern in this, but I can't find it. 

When I move the speaker setting from Realtak to the LG Monitor speaker, the issue remained, unless I start to play audio.

My brother has the same problem with cracking sound on Acer aspire vn7 when the charger gets plugged In. After you take your charging cable off the problems seem to be temporarily fixed. However, the laptop stopped working and the diagnosis was Motherboard Sadly. He was running Office 2019 and suddenly the laptop stopped working. Take god that laptop was under warranty period

Uninstall the Realtek driver in Device Manager. Don't try to re-install anything. Shut down Windows normally. Turn it back on and let Windows re-detect and automatically re-install a fresh copy of the driver.
