Xruns occurs when playing empty space

When Arduor 5.10 is playing track with wave data it’s OK. But when no sound data in the track, XRUNs occur.

JackEngine::XRun: client = ardour was not finished, state = Triggered
JackAudioDriver::ProcessGraphAsyncMaster: Process error

How to fix it?

probably a plug-in that doesn’t handle denormals properly?

Very good suggestion. I was very surprised when my plugins got 100% CPU load on zero input. Now it’s already solved.

Thank you, it works.
