recording slowing down

When I am recording using my pioneer ddj sb3 with my windows 10 it starts out fine but when I play it back it starts slowing down. I am recording on Wasapi and my line in thru IRIG Stream Please help?

How much is it slowing down?

Does the pitch also change?

Does the problem happen if you record directly from a microphone without the iRig?

How is the iRig connected to your computer?

Why are you using WASAPI?
