The clicking and popping is still here on 11.4 as well
- super disappointed with Apple.
The only solution is to keep an audio source "working". The QuickTime New Audio Recording does work. The second option is to just restart.
Off and on this audio popping when the sound chip "goes to sleep" has happened right back to the first MacBooks - at least. They fix it. They break it. They fix it. They break it.
This particular "variant" of the bug is only happening after a full computer sleep. I took my laptop out of the office yesterday to work somewhere else. Came back with it, plugged it into the LG5K and popping was back. Ended up with the QuickTime fix because I had work to get done and didn't want to restart.
