Recently, I was troubleshooting the source of jumpy latency between my laptop and local network devices. I discovered that the source of it is Audirvana Origin app. When it’s running, ping to my local devices is jumping between a couple of milliseconds, to hundreds of ms. It happens without active library synchronization taking place.
Could someone explain me what’s happening?
Here I made a screen recording that shows the issue: Audirvana Origin latency issues - YouTube
I use gping utility to show ping graphs.
