Having ThreadSchedulingModel set to 2 may "look" nicer on the CPU meter but I've found it actually makes audio performance worse. I have a quad-core (8 with hyper threading) laptop and the 0 setting works the best. Of course, there could be other issues that could be causing audio clicks/dropouts. For instance, on my computer (it's actually a 2016 MacBook Pro running Boot Camp ha ha) I have to disable the ACPI battery driver (that monitors the battery level), the Wi-fi adapter, and the onboard sound to get glitch-free audio performance. The battery driver is the worst culprit. You'll want to download the LatencyMon program (do a Google search) and run it to see if other drivers are interfering with your computer's audio performance.
