It really shouldn't the only reason it should crackle is if you turn the volume past 0db because some audio sources might peak.
Your issue of audio crackling is usually a non-grounded auxiliary or, a high memory latency / memory bug.
When I was on z97 and had my memory set to 2133mhz [a very high xmp value for ddr3] the audio constantly crackled when running certain applications. This can also be experienced when running with a lack of buffer while using an ASIO driver.
Completely unrelated to the plugin itself but maybe exacerbated by it.
