    SPDIF to Analogue converter - Intel D945GCLF2

    Hi guys,

    I have the Intel D945GCLF2 motherboard, which has pretty low output analogue ports.

    I can't put a PCI sound card into the board, as I have other uses for that PCI slot.

    I was looking at options for using the spdif output on the motherboard, however my amp is the usual analogue input.

    What do people think of using something like this:

    http://www.jaycar.com.au/productView...x&form=KEYWORD

    I could mount that out right next to the amp, use a really short output from that unit to the amp, minimising analogue transmission distance, and use the spdif from the motherboard out to that unit.

    Its 70 bucks Australian, which I don't have an issue paying, and I could just use the 5V output from my computer power supply to power it.

    It states that it only converts uncompressed digital audio, is this a problem? Does the intel board output uncompressed audio on the spdif ports? or is it only compressed format?

    I'm not looking to output 5.1/7.1 with this setup, so dont need to worry about Dolby DTS or anything like that, and it is probably more just to get past the horrible clipping and bad audio I get off the analogue ports, until 2k1Toaster releases his usb amp, at which point I am probably going to jump all over that

    Nice find. I'm waiting to hear more on this myself, since I have the same motherboard. I've been rockin' a Sound Blaster PCI card myself for a while because of the ability of it to use the Sound Blaster proprietary the Digital I/O module to input my Sirius stream into the sound card.

    it turns the lower PCI card some millimeters above the onboard audio connector and CPU heatsink, so there is no space problem

    Thanks FPeter, thats one other option as well, however I like the idea of the SPDIF converter, as I can run an optical out over to the amp, and bypass any interference from the analogue outputs.

    This would even let me house the amp in a totally separate place in the car, and not have to run long analogue cables out to it, I could just run an optical cable instead.

    You can try it with the integrated SPDIF optical output, but dont be surprised if it gives very low quality: jitter problems, etc... in this case, You need something much stable output like a good USB soundcard / transport with optical out, or a PCI card, like ASUS Xonar DG or similar card with a better chipset than a simple integrated one...

    here are 2 other option for DAC-s with optical in: a cheaper stereo and an expensive one with more channels

    My local Jaycar had a pair of those for $20 or $25 (each) a few weeks back...

    Today I got a dual 60A breaker with manual on/off & voltmeter for $20.
    Apparently people prefer fuses!

    chester on what goes out the SPDIF...
    well 1st run a Modern OS, so that is NOT XP, only vista or win7
    win7 of course, that will properlly manage the audio
    and you can set the optical out as the playback device and
    all pcm audio will go out the optical
    make sure u have the latests drivers for that motherboard
    for the realtek HD audio

    Xp who knows.. will only be as good as the drivers with no real enforced standards
    unlike vista and win7
    -Thanks

    Thanks Mitch, I'm running CF on Win 7, so that covers that angle!

    I might swing past Jaycar next time I'm in the area and see if I can grab one, see how it runs.

    Unfortunately I can't test on an AV receiver, as I haven't got any equipment that supports optical lol.

    But thats okay, for this price (Or less if oldspark is right), its a reasonable cost to "suck it and see".

    Ill report back when I have given it a try, and let you know if its worth the money

    I thought Jaycar also had the SillyChip kits.... Two-Way SPDIF/Toslink Digital Audio Converter (June 2006) or Two Toslink-S/PDIF Audio Converters To Build (October 2010)... (alas no).
