I'm currently using an Audigy 2 and connecting it to my Onkyo receiever with a Y-Adapter. Now, would it be better if I connect the Audigy to the receiver's analog input or to its digital input (with a single coax cable)? I mainly use my PC for mp3 listening, barely any gaming or movie watching. Thanks in advance for any help. PS: For some reason i get clicks when I connect it digitally.
