mdsonyfan

Hello, I have a sony net md wakman mz-nf610. Now im trying to record from my turntables. I have it plugged into line1 on my mixer. And I plug the other end into line in (optical) on the sony walkman. I do the r set, r mode, lp2, then hit the t mark button and play button and it starts recording. Only when im done and play it i don't hear anything. Help please????
