New sounds causing weird lag spikes in Play testing, only in studio!

When i introduce a new sound into Studio (importing them through the toolbox), and press Play (to test my game), sometimes when playing the new sound, and just randomly through my testing, I get weird lag spikes (frames dropping) that aren’t caused by anything else. Doesn’t happen on live servers, just in studio. It’s happened with every game i’ve developed, so it can’t be specific code or anything im doing that’s causing this. After a while (not sure if i have to close studio or not) the lag spikes will go away, as the sound is no longer new. This happens almost any time I introduce new sounds into my studio place. Maybe it’s a weird caching thing?
