Can someone help a n00b please. I bought the Sony htk-475 pack, and was looking forward to digitally connecting it to my Soundblaster Audigy Player. The problem is that the digital connection on my Soundcard is round (SPDIF output) and the one on my AV is square! I am using analogue leads at the moment, but is the only answer to fix this to buy a Soundblaster card with optical out or is there a lead to convert it ? Thanks in advance, A newbie.
