i bought an atlp120 usb turntable, and when i dont have it playing through my headphones it will record in stereo (using audacity) just fine, but i cant hear the music playing. when i set it so that the music will play through my headphones, it only comes through the left channel, and only records in the left channel. i have it connected directly through my computer by usb, im not using rca cables or anything. what the hell is going on? its really pissing me off cause i cant find any answers online
