I'm trying to figure out the best way to connect my creative x-fi xtrememusic soundcard from my PC to my Onkyo SR806 in order to get the best quality sound from the mp3's on my computer to my speakers on the receiver. The PC and receiver are in different rooms, so the cable length, whatever type it will be, will be about 35 feet long, give or take. There are the outputs for the card:
As far as I can tell, I have 3 options:
1) Connect analogue from the line outs 1, 2, and 3 to the receiver for 5.1-7.1 sound.
2) Connect (analogue?) line out 1 to the receiver.
3) Connect digital from "FlexiJack" for "external digital audio devices that accept stereo PCM or compressed Dolby Digital/DTS Bitstream from the S/PDIF output."
All the jacks are 3.5mm. From what I have read on various forums, option 3 with the digital signal can only be stereo, not 5.1 or better. But since I will be listening to music, is this a big deal? My other concern of course is the length. I do not know if that is an issue. Please help!
