Windows 10 mouse pointer pause/stutter and audio crackling issue.
Things tried so far in the order done, and their result.
1) Searches indicate that it can be fixed by un-ticking "Enhance pointer precision" in the "Motion" section of the "Pointer Options" tab of "Mouse Properties" in the original version of "Control Panel".
This appears to work so far, the clicking audio also appears to have disappeared with this one change.
I'm still not convinced, and I'll update this after a day of use.
To do this, click "Search" on the task bar, and type "control panel" in the search box, then click on the result to open up "Control Panel". Click on "Mouse" in "Control Panel", and then click on the "Pointer Options" tab now you will see the tick box for "Enhanced pointer precision" just under the pointer speed slider. Remove the tick from the box and click "OK" at the bottom of the window.
Now do the things that used to make the mouse stutter and see if the issue still exists.
It appears that this is a fix that must be repeated if the issue returns. By that I mean to say that recently the audio clicks and mouse pauses returned, after having no problems for some months, like the "cat in the hat" in Dr Seuss's book, it came back. The trigger to cause it to reoccur is unknown, possibly a windows update. However I reread this post and confirmed that the "Enhanced pointer precision" box was still not ticked. It was not ticked. So I tried the old trick of turning it on, saving the setting as turned on, turning it off, and again saving the setting as turned off. Weirdly enough that appears to have stopped both the mouse pointer stutter, and the clicks in the audio.
