Just as others have experienced on the X1 Carbon 6th Gen, I am hearing Speaker Cracking Noise. It seems like there was a BIOS fix that solved this as seen on this board: https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/Thinkpad-x1-Carbon-6th-Gen-Speakers-Cracking-...
The cracking doesn't happen when not plugged in.
@Lenovo Support, please advise.
