"Preview" of audio processing not audible?

Every audio process fails to make sound when I click “preview.”
The button changes to “stop” and I see a little activity on the transport meter, but nothing comes through my monitors at all. Inserts and sends are working.

Running two stereo tracks, a compressor and a reverb. This used to work back in February…

I updated to latest version of 8, but it did not help. I tried disabling control room as advised on the GS forum. No improvement.

Anyone familiar with this? Thanks!


Make sure you are using Control Room and Monitor 1 is your main out, please. Same as other Previews, this one is routed to the Monitor 1 bus.
