I'm hearing digital clicks in preview that aren't in the exported audio.

So I just got a brand new computer, and I've used Premiere several times on the new machine without a problem, but diving into my first project in Audition, I'm running into a very odd problem. Every time there's a transition between two audio clips in Auditioin, there's a strange digital pop in the preview. To be clear, this pop doesn't seem to be present in the audio itself (e.g., artifact sounds bumping up against each other in the edit). It's just the same digital snap/popping noise in between every two clips. To test my gut feeling that this was something in Audition preview, I exported the audio, and sure enough: no clicks. 

It's almost like the Audition preview screen can't keep up with the audio it's processing, and those are "thinking clicks" or something. I've been editing the exact same kind of audio for several years now in Audition, and I never ran into this on my old computer. Any ideas for a hardware setting or maybe processing speed setting that I could tweak to improve this would be very appreciated! (For what it's worth, this new computer has better specs in every way than my last machine.)

I can't really work on my audio until I fix this, since I typically have an edit every 8-10 seconds on a 20-minute piece of audio, and it's impossible to tell how smooth the actual exported transition will sound with this click in the way. Thanks in advance!
