If the input line signals are moving normally then your turntable and the USB are all working as they should. Download the latest version of Audacity (it is freeware) and install it following these instructions…

Double-click the downloaded DMG to mount it.

Do not double-click the “Audacity” folder in the DMG window. Drag the entire “Audacity” folder icon to the /Applications folder icon on the right (or to any other location of your choosing).

Eject the DMG at bottom left of Finder, then launch Audacity.app from the “Audacity” folder in /Applications or from your chosen location.

Known Issue: Security settings on OS X 10.7 or later/macOS may block Audacity being launched, due to changes made by Apple. [this should not bother you since you are running OS X 10.6 — JMB]

To permanently enable Audacity launch, right-click or control-click on the Audacity application in Finder, choose “Open”, then in the dialog box that appears, choose “Open”.


Then you can tick SOFTWARE PLAY THROUGH BOX then OKAY.
