You can share your Pro Tools audio into Zoom using
Source-Nexus!
Simply put the Source-Nexus plugin on an aux track or your master fader, then set the Zoom mic to your Source-Nexus send audio device ("Source-Nexus A" by default) and you're sending a live, low latency feed directly from Pro Tools into Zoom. Works with virtually any other application, and multiple applications simultaneously as well.
Check out our latest Pro Tools and Zoom Source-Nexus tutorial on YouTube. The video shows the set up on Mac but it is largely the same on Windows.
