Sounds like you are listening to your timecode, which happens when your software is set to thru mode, you have to choose one of the other modes. Above the white “clock” there should be 4 buttons: ABS – REL – INT – THRU. Probably Thru is on now. This is the mode you need when using regular vinyls (i.e. with music on them). The other modes you have to figure out which works best for your workflow. Relative is the most used I think.
Hope that helps.
As far as needles (and timecode) goes, be prepared to spend about 100 bucks or more a month on new needles and vinyls.
