Hi. I've got a Creative Sound Blaster Audigy pci 5.1 sound card.:lol: What i don't understand is, before i connected the Digital CD audio cable to the CD_SPDIF, i was (according to windows settings) able to make use of 'Digital audio out' for my dvd drive. I presume it went thru the EIDE cable to the motherboard? because i've NEVER had an 'analog' audio cable connected to my DVD drive / Sound card EVER. My question is: If I'm right in thinking that the Digital audio went thru the EIDE cable, then what on earth dose one need the CD_SPDIF for? Is it because it's better in some way, than using the EIDE cable to send the Digital audio to the sound card? Less taxing perhaps?:uhoh: Is there any benefits to either route? & how can i tell if my computer is actualy using the CD_SPDIF or the EIDE cable?
