Hamzaaa, did that cracking sound start on your TV after that update? I purchased mine back on Dec, 2019 and I have already had some months with that sound, too. I understand a Firmware update should only affect software and not its hardware.
Yes, it just started after the update because my AV Receiver don't support eARC and the Audio changed due to the update from PCM to forced Dolby Digital+ (in some internal Apps like Netflix and Disney+). Normal TV channels work well.
