I have been using the board since Feb. 2022 and have had no problems so far. I also had the crackling in the audio in the past (with other boards), with audio via the jack plug 3.5mm, if this is somewhat defective. You notice this when you move the cable or turn the plug. It then crackles and is also gone in certain positions. Interference with electricity can also be the reason.

So far, as mentioned, no problems with this board.
