Just got a new record player today and it comes with pre-amp RCA outs. I hooked those pre-amp outs into a RCA to male 3.5 mm converter. I then tried to plug the 3.5 mm male in the line-in blue plug in the back. However, for some reason, my computer outputs audio through my audio-in and that didn't work at all.

Currently, my record player is playing through my speakers using the pink microphone jack and turning the volume all the way up. Yet, even though the computer volume and microphone volume are ALL the way up, the record player is really quiet.

Can anyone help me here?
