I've been building computers for

awhile and I have always installed the S/PDIF cable, but does the computer really utilize it when converting over sound? What purpose does it serve on DVD and CDroms?

I haven't used it for years and still play CD audio. Try removing it and if it still works then you are golden.

I think the deal is that once the CD players used to decode the audio and send em over that cable (cd analogue?), nowadays the data is sent to the player and it decodes it, therefore no cable is needed (cd digital?)

Electric is correct. i haven't plugged that is in years. Its only used when you play CD's direct from the CD-Rom.

ever since I heard about that whole S/PDIF thing I never installed it on any of my computers. Mind boggling that thing you call S/PDIF but I have been building computers since 2000 when I got into it heavily. I guess I can call myself an enthusiast now :D:D:D:D:D.

Hmmm - i dunno what the hell happened with my first pc, but after putting that cable back in .. (somewhere in the wrong place i'm guessing) the cable went up in smoke and melted off all the casing :p so i never used one again

S/PDIF: Short for Sony/Philips Digital Interface, it's a standard audio file transfer format.

S/PDIF allows the transfer of digital audio signals from one device to another without having to be converted first to an analog format. Maintaining the viability of a digital signal prevents the quality of the signal from degrading when it is converted to analog.

Read this and this :)

Actually that cable is an analogue cable not a digital one. The os/computer now carries the signal digitally through the pci bus now.

There are two connectors, one four pin (analogue) and one two (methinks) pin (digital).

Methinks you correct. I have both connected to my SB Live sound card.



Internal digital SP DIF/SP-DIF audio cable for digital output from CD-ROM, DVD-ROM, and CD-RW drives to advanced sound cards. Also called S/P-DIF and S/PDIF cables.

This cable is used for digital instead of analog audio output. The conventional 4-pin audio cable/connector is analog.

you dont nede any cable except the ide/sata/scsi on optical drives these days
all will play the audio over the data bus. 99.9999999...% of drives dont even have the digital output wired up internally :p
