I’ve been working now for three days removing everything regarding check for updates stuff, and similar in my computer to get rid of hourly dropouts I got. And it even is not problem in Sonar, I had no dropouts there from these checking of updates, none, not ever.
It probably happend to you all at some point.
Since no sign of this in Sonar, I figure something is overly sensitive in how Cubase handle sync.
EDIT: Conditions just having transport in stopped in Cubase, and performance meter up - you see when this hourly thing comes, you get red peak realtime.
If running playback - severe crackle at this hourly thing.
If recording - transport stops and show a sign about dropouts.
Doing the same in Sonar, playback and record - not a sign of crackles or pop or anything.
So it’s not dependent on project in Cubase, since just having transport stopped - same thing.
You can have ASIO Guard on or off - higher ASIO buffer - same thing.
