Slow audio problem

I'm thinking about starting a new project on Adobe Premiere. Just a light video I'm going to mess around with and edit to kill time, but for some reason, Whenever I load up the assets and put them on the timeline the audio becomes slowed down. The duration and everything remains unaltered but the audio just becomes very low-pitched, as if it's slowed down. I've looked around and found it's some sort of issue with the bitrate, but meddling with those settings have yet to yield results. Right now I can't find anyone else experiencing the same issue, (save for a few old forum posts that didn't help remedy the problem) so it's difficult for me to find a fix. If anyone can tell me what's happening and how to fix it I'd be very grateful. Thanks.
