Pops, clicks, and dropouts are often buffer-related issues (usually from having your buffer size set too low). Check your Buffer Size setting for your interface/audio system. Often, this can be accessed through either a dedicated software control panel for your interface, or from within your DAW software (some DAW software refers to buffer size in terms of Latency, so if you don’t see a Buffer setting, look for Latency).
In general, larger buffers are more stable. Try increasing your buffer size until the problem goes away.
There are also several settings you will want to make in order for audio applications on your computer to run optimally. Check out our Optimization Guides:
