I've noticed that when charging over USB with headphones connected via the headphone socket, you can hear a loud buzz if there is no audio playing.
I first thought it was whenever the audio DAC was not playing an audio stream: the buzzing disappears the instant you play any audio or any notifications play. The buzzing returns the instant the audio stops.
However, I was listening to a YouTube video earlier (https://youtu.be/b753qCxQcGw) and I noticed at 10 seconds in the the buzzing very briefly occurs - in a momentary gap between the intro and the start of the main video.
This seems to be due to null samples in the audio stream and is a reproducible behaviour. Playing the video at half or quarter speed makes it easier to notice the effect.
This is not a fault of my headphones, I'm using regularly serviced HD25 and HD650 Sennheisers.
So, from my crude tests, it seems that if the DAC is not initialized - or it is initialized but is decoding null audio samples - the design of the main board reaults in the audio output passing through electrical buzzing/humming from the charging circuit as audible interference to the analogue headphone output.
This is not very impressive design for a £700 flagship handset. Samsung, please address this.
Have you tried a soft reset on the phone? To do this, press and hold the 'Power' and 'Volume Down' buttons until the phone restarts. This will end all processes and give the phone a fresh start. Let us know if this makes any difference.

Samsung 10+ 1tb version. Same buzzing sound here, very audible when charging. I use an amp with hi-fidelity headphones so it is really annoying when a song is very quiet or not at full blast. Buzzing does not occur when not charging.
I did not have this problem with my old 7 edge, USB-C issue?
