Hi I played a gig last night and the turntables didn't respond, I set the audio up properly and nothing only a buzzing sound when I put the needles on the record, the wave also didn't respond to the movement of the needle arm, is there a glitch in audio 10? So frustrated and lost money as well as my reputation as I didn't get to play and walked away in shame…I spent 4 hours trying to get the sound card to communicate with my turntables what must I do Where am I going wrong?
