I am attempting to create MP3's from my tape collection using my sound card and CD Spin Doctor software. However, the tape player I am using only has a single line-out jack (for headphones) and a single line-in jack on my sound card. Consequentlly, when I play the MP3's they only come out one speaker. Is there a way to get this to record in stereo with only a single line-in and a single line-out? Do I need to get a tape player with 2 line-out jacks? The MP3's themselves sound fine except for the fact that they only play out of 1 speaker.
