Audio recording oddities

Hi all,
I'm trying to record a simple audio voiceover into Resolve (I've generally captured audio into other apps but thought it could be handy to go directly into my editor). When I try to record however it works fine for a few seconds then skips ahead a few seconds before continuing to record. The resulting file is distorted. It's very strange and hard to explain, but you can see it at

(this is being recording into an empty project, but the same thing happens with other media on the timeline as well)
I'm using Resolve 16.2.7.010 Studio with a Focusrite Scarlett 2i4 (which has no issues in several other programs on my Windows 10 PC). The 'unskipped' bits of audio are captured fine, and monitoring works fine until I hit record and it does this every few seconds - the longer I leave it recording, the longer the 'skips forward' get.
Anyone have an idea what's going on here??
Thanks

Is your Scarlett's sample rate set to 48k to match Resolve?

Just a follow up in case anyone runs into a similar issue, this turned out to be a mismatch between my timeline framerate and clip framerate... I've gotten too used to working with Vegas Pro, where you dump anything on the timeline and adjust the project or render framerates at will and it conforms it on-the-fly, but Resolve is a little more particular.
My eventual fix was to select and 'cut' the entire timeline, adjust the project framerate, then create a new timeline and paste it all back in... a little annoying but got there in the end.
