cdrom s/pdif to receiver

[bjlockie]

I want to hook up the digital out of my cdrom to my receiver.
Can I use one of those motherboard s/pdif brackets to allow me to use a digital coaxial cable?
The brackets that are normally used to connect the s/pdif of a motherboard.
I have an LG GSA-4163 cdrom.

Yeah but may have to change the plug and/or lengthen the wires. Usually, the ROM drive is connected to an audio device (on-board or soundcard) and then its outputs are used.

The S/PDIF output is not even common on drives anymore due to cost cutting which is a pity since the direct connection is obviously preferable to loading the PCI bus with the data cable transfer method.

Realistically, you're only putting a very slight amount of data on the bus, especially compared to something more intensive like playing a DVD. I really don't miss SPDIF connections on my CD-ROM drive, personally.

How can I tell if my receiver expects 5V?

Why go through all that trouble when you can just get any ol' sound card for $20 with a digital out if your motherboard doesn't have one already...

The old analog and SPDIF outputs on the drives themselves are largely obsolete. Some OEM's still connect them but there really isn't any point.

Perhaps the voltage question can be avoided with a bracket that has electronics -particularly having both coaxial and optical. Before going to trouble though, have you confirmed the drive has a functional output?

The soundcard needs spdif input to connect the cdrom AND spdif output to connect to my receiver.

Digital audio can be sent over SATA or IDE cables. No need for a separate connection.

mmm, cool.
How do I verify a soundcard is getting digital audio from my cd.

There is no means to transfer analog audio from the CD-rom to your sound card without attaching the analog audio cable that some CD-roms had on them in the past. If that is not attached, your sound card is selected as your default audio device in sound settings in the control panel, and you have "enable digital audio" per the following:

you are getting digital audio to your sound card.

Basically, if onboard audio is disabled and you are hearing sound from your CD's you are getting digital audio.

Oh, the analog cable is not attached.
What the purpose of the analog (4 pin?) connector on the cdrom?

Wayyyy back when windows couldn't transmit digital audio over the IDE cables. Connecting the SPDIF directly to the sound card was the only way to get digital audio from your CD-rom drive to your sound card.
