Recording a vinyl record into Audacity (msg for DVDdoug)

there was an answer to a post of mine by DVDdoug, which I didn’t get to reply to in time, and it was closed. so i just want to say thank you, but i couldn’t find how to send you a message. i think the answer was not to connect the turntable to both the amp and the computer at the same time. i know there’s a switch on the turntable, and i thought that would be enough.
