    Frankino..

    I'm having trouble when I hook up the high/lows to the epilog I get no sound playing.

    I just did something that may seem really stupid but it has SOLVED my problems with CF and KxDriver.

    Instead of using the Audigy2 with KX as my output device...

    I re-enabled my on-motherboard sound device. And ran the line-out from my motherboard into the Audigy's line-in.

    This way, CF only has to deal with the onboard sound (in my case, an Nforce2 / Realtek chip) and KX is free to go on its merry way doing exactly what it's supposed to do: processing input sources.

    This fixes my issues with resuming from hibernate, and I've skipped tracks dozens if not hundreds of times without hanging.

    I had this theory that the problem is that CF doesn't close channels in a KX-friendly manner, and as a result eventually the KX device gets overruns of some sort. I'm no DirectX programmer so bear with me.

    Rather than having "FXBux0/1" (Windows sound output) as the source to my processing chain, I'm using "AC97 LineIn" so Kx never has to open and close sound channels... it just deals with the continuous stream of WHATEVER comes off the onboard sound chip.

    Flawless. Except I really dislike the idea of going Digital->analog->digital->DSP->analog. Way too many steps.

    Next step is to connect the motherboard's SPDIF output to kX's SPDIF input. If I can do this, everything stays in the digital domain until it goes out to the amps. I can live with that. And it should work just as well. Just don't have the right connectors yet, so I thought I'd try it this way.

    LOVE IT.

    If you're using KX and ready to abandon Centrafuse (as I was) this is a HUGE step away from all the bugs we were dealing with.

    Setup attached. Not as fancy as the other one posted, but I wasn't going to spend much time on this until I got my front end working right. NOW it's time to get crazy!

    an advise, start by drawing a straight line between inputs and outputs, keep a low volume and see f it sounds. If it does you're fine to go ahead and place the various filters between in and out, it it does not sound try to place a peak meter and see where the sound stops, doublecheck the input/output and see if you're using the right wave mapper (kxproject has 4 wave mappers iirc)
    by the way take a look at the official site, there's a bunch of good startup guides

    good idea, it requires work and luck (with kx you need a lot of it) but it should be ok, there's a couple of people I knew that used two sblive linked together by spdif to achieve 12ch output

    Doing it in analog required virtually no work OR luck. Kx was designed for studio audio applications, so it really seems to be happier working in this capacity as a "processor" rather than as an output device.

    I'll try to get the SPDIF going today. Fingers are crossed...

    Just finished hooking up thru SPDIF connection from the motherboard to the Audigy.

    Flawless!

    No CF vs. KX problems anymore! Music after resume! No freezing!

    So does this also fix the problem that CF was having when doing volume up/down with the kx drivers?

    Haven't checked yet, but it SHOULD since again, CF isn't even "seeing" the kx-controlled card.

    Ok sounds good. For some reason I can't install the drivers for my desktops mobo sound.. I have kx on both my desktop and car so I like to test before I do it in the car. Thanks for the find though!
