Crackling sound when recording from ZOOM H4N

Which Zoom driver did you install? I can only find their ASIO driver which won’t work with Audacity as shipped unless it also exposes a WDM driver.

If you found the driver worked before, and rolling back does not help, have you tried uninstalling then reinstalling the driver that you obtained?

Have you tried “Alternative settings if crackly recording or playback occurs” in the green box a few scrolls down on Missing features - Audacity Support ?

Note that Zoom say

Some audio problems may occur when using the H4n as an audio interface for some laptop computers based on AMD chipsets.

As far as I can see your laptop has an Intel chipset, but I’ll mention it for others who may read this.
