My laptop once had this issue, where it would have audio dropouts/crackles. I thought the issue was resolved because they disappeared one day. But recently I had to attend a zoom meeting, and the crackles came back. There were a couple throughout the meeting, and then after, whenever I had any audio on. Even after a restart and windows update, they are still present.
On the meeting i used the logitech c170 webcam via usb, and the built in laptop mic.
