Video playback Stutters/Freezes on Mac mini upon changing the system volume. Hello, For the past few months I have noticed a problem where video playback stutters or freezes for a second or so whenever the system volume is changed. It seems to be worst when I use the keyboard volume controls, but there is also stuttering if I use the mouse to alter the volume slider in the menubar. The last time I updated the OS the problem seemed to go away for a short time but has since returned. The issue happens in both Safari and Chrome, incognito or not. It seems particularly bad when the video has not buffered or is a live stream. It's quite frustrating and I've taken to using my external audio mixer's volume control to alter volume when watching videos. [Re-Titled by Moderator]

What have you tried so far? What kind of Mac is it (click on "About this Mac" in the Apple icon at top left of screen).

A safe boot followed by a normal boot sometimes fixes weird problems.

An SMC reset sometimes does.

Run the etrecheck program (lots of discussions here have links for it) and post report.

Good luck...
