I have noticed on occasion I will lose all audio playback.
Nothing produces sound when this happens. The meters dont even register as if sound is running in them at all.
The midi tracks still pulse signals but obviously no audio from any type of track.
When this occurs cubase will also pause around every measure like it is tying to catch up with itself. then start moving again.
This either happens on load of a project or if a a VST of some kind crashes.
The only fix is to restart cubases and reload many many times or reboot.
Any ideas what would cause such a thing? its realy really terrible and frustrating not to mention time wasting.
