CC causing stutters / audio hicup

Hey there fellow simracers. I tried to find a reason for this odd problem i got here. Whenever i use CC (doesnt matter what sim - thats ACC, AC, RF2 and R3E) sometimes the audio will crackle when the chief is talking to me. This makes the sim freeze for a second or two. Its not happening all the time and i dont see any error messages in the log. When racing in any of the sims without using CC then the problems gone. Dont know what other information there is that would help here but maybe someone's got an idea. Thanks for your help!
