I suggest we start by eliminating some variables here. Can you please try to start playback to your Core’s System Output zone and verify if the issue occurs there (no HQPlayer/DACMagic in the mix)?
Hi Noris. Thanks so much for getting back to me so quickly. It is really appreciated.
It sounds (no pun intended) like we are going to have to work our way through a number of scenarios/use cases.
It could take a while because the problem was intermittent. Do you think it would help if I try and ‘stress’ my iMac by loading-up Safari and running a couple of virtual machines to see if that increases the frequency of the problem?
A couple of quick questions:
Is there a way to prioritize Roon processes over other ones?
Is there a way to prioritize Roon packets over Thunderbolt 3/USB/Ethernet?
Does Roon pass any processing to the graphics subsystem?
I still suspect that Safari is a resource hog one way or another.
I would wait until this issue occurs again and then check your other zones (such as System Output) to see if they still work as expected. Then we have narrowed down the possibilities.
