No pause in Rack 2?

In Rack 1 there was a pause option under sample-rates.

I cannot find the pause option in Rack 2, anyone knows?

That feature was removed in Rack 2 due to the changed audio engine.

alternatively, you can temporarily disable the audio interface module, thus disabling the audio driver, I’m not sure it is the same as the old pause but it definitely reduces the load on the cpu considerably.
