The same thread already exists but i cannot see it anymore so i created a new one. Someone suggested to laucnh Console whenever a audio dropout occured and to look for "timed". I did just that and in fact "timed" occured at exactly the same moment as the dropout. Does it mean a have to disable time synchro ?

That's what I do. I enable it once a day to keep the clock current.

timed runs every approx 30 minutes. timed itself does not directly affect audio. each timed run results in multiple log lines in console.

Immediately after timed has started its run, you might or might not see multiple kernel calls affecting IOAudio. This is what causes the audio glitches. The audio system is being stopped and immediately restarted.

Turning off time and time zone synchronisation does not in itself stop the calls to timed but it does seem to have some effect on whether or not you hear any glitches.

I have also recently turned off ALL notifications and this seems to have had a beneficial effect. I still see the audio system being stopped and restarted occasionally but usually do not hear a glitch.

I realise this all extremely nebulous but it seems to just be like that. Nothing is definite here until Apple actually fixes this. It could also all be just in my mind :)

No it's not just a mental image. I really do not have any more glitches since i disabled automatic synchro. Rolling Stones : "Time is on my side".

I just got my 2018 Mac mini (Core i5, 256GB) and it has severe audio glitches too. Not just on the built in output but also when I use my USB interface, and also on the LG Ultrafine 5K built in speakers.

I have no audio issues with my 2018 Mac mini- 3.2ghz i7, 32GB, 1TB.
Audio interface is Focusrite Red 16 Line via Sonarworks.

Unfortunately I can’t imagine Apple will fix any of this unless it is being reported to them on a mass scale. They seem to be too busy thinking about their phone or putting other fires out.
