Lenovo Desktop Ideacentre 3 Windows 10 Phono Pre Amp Sounds Like Tunnel.. flanger like... help?

Recently set up a Lenovo Desktop Ideacentre 3 and went to check Audacity (Using latest 3.0.0 version) with my Phono Pre Amp TC-750LC
and the sound is awful. The classic tunnel and somewhat flanger and muffled sound - sounds just BAD. Turntable & needle are fine. I suspect it’s some kind of setting I have incorrect?? Never had this issue with Windows 7 but it’s been a few years since re-installing Audacity. I realize this may be a beaten to death horse of a topic but can anyone help me out here? Tried searching but not finding recent issues like this. There has got to be a way to get proper sound coming in.
