To troubleshoot further, - Why do you relate the sound to ground wire? What was your troubleshooting to make this determination?
- is your ground connection secure and tight?
- Can you measure the resistance from your ground wire to a different bare metal body part and post here?l
- You mentioned that the sound has some relation to door opening. By Any chance any wires are getting pinched or pulled during door opening?
- Do you see any screen flickering when the sound is there?
- Do you have subwoofers installed in your car? by any chance is the sound coming from Subwoofer?

I'm not OP, but I assume we have the same issue from what he's describing after installing an aftermarket Carplay unit. The unit itself doesn't use a ground wire - one is included with the cable to connect aftermarket reverse cameras, which I didn't use.
I unplugged an aftermarket sub/amp I installed, and the issue persists, though not as enhanced without the loudness of the sub. This is directly related to the Carplay box as I didn't have this issue until now.
For me, it's a persistent hissing you'd typically get at high aux volumes, regardless of my actual stereo volume. When I open/close doors, or turn on the car (anything to trigger the powering of accessories), I get a loud pop through all speakers. I assume it's some resistance of the head unit or amp turning on.
