    Digital Output and Mic In/Line In

    Is it possible to use your Stereo jack input when using digital sound.

    Specifically i am trying to hook up my RadioXtreme USB FM to the Mic in of the Via M10000 and have the sound output through the digital Coax cable and interprited by the surround sound processor (Panasonic CY-AC300EX)

    I am not having much luck

    I can set up Radiator with RadioXtreme on my laptop and it works great (not using digital sound)

    Any hints/clues/comments are welcome

    Cheers

    I tried it too, with few success. The input signal (Line or Mic) seems to be looped to the Line out.
    Maybe it is possible to record the Mic signal and play back at the same time.(?)

    That sucks. Maybe i should write Via support on this one. How about using the CD IN pinouts on the mother board? Do you think that would work?

    Has anyone sucessfully gotten a Line IN (either mic/line in/CD in) while using the Coax SPDIF port?

    This is going to be a big problem becasuse I want to use the a MIC for voice controls and use a line in for the radio.

    Crap... any other comments or help

    The main thing I am concerned with is having the ability to have the onboard sound card have inputs while outputting the sound digitally using the S/PDIF.

    Is using the CD-IN pinnouts on the motherboard an option?

    Thanks
    This is what i wrote to VIA. Hopefully i will get a solid response soon

    Hi Ryan, It is possible to setup the audio system as you would like it to be. First, you will need to set the RCA Video or S/PDIF Select jumper to S/PDIF. Then, you will need to enable the SPDIF option in the volume control. Make sure the Smart 5.1 option is not check if you want to use Mic In and Line In. Best Regards, VEPD Technical Support
    ================================================== ======
    I am going to write a response saying that it doesn't work because I have it setup this way. I have the S/PDIF jusmper enabled and SMART 5.1 unchecked

I have the Smart 5.1 Unchecked as you mentioned and still no sound out of the S/PDIF from either the Mic or Line In Jacks.

    I know that the sound is getting actually getting in because if I plug headphones or speakers directly into Line Out Jack I hear the sound from the Line In... However I only hear all other sounds through the Coax S/PDIF.

    I want the Line In to passed as digital data to my Digital Surround Processor just like all other audio.

    Perhaps using the CD-In this will work?

    Please help me with this

    And thanks again,

    The first response of VIA is a typically standard answer...

    Try to use the CD-In but I guess it won't work because I have tested it in a similar case: when a stereo signal is send to the CD-In the 5.1 analog-output on the motherboard only puts stereo at the middle jack out. That means the signal isn't converted to a digital format (-> upmixing to 5.1 impossible). It is only looped to the line-out.

    OBTW: I suppose the digital s/pdif is only stereo signal (in case of the VIA Epia M10000) and not 5.1 because when I connect the s/pdif to my extigy (can be used as stand-alone) the extigy only put the front stereo signal out.

    most sound cards mix in the analogue signals after DAC (wave, digital CD, SPDIF in) before outputting in as analogue via the line out. hence u will only hear the digital source from SPDIF out even though you can hear analogue sources in your line out.

    some sound chips allows for digitising of analogue sources (call stereo mix) before mixing them with the digital sources. for these sound cards, you CAN hear analogue sources on your digital out. but EPIA isnt using one of those.

    it's possible on some sound codecs which allows analog signals to be converted before mixing with other digital sources. for these cards, you can hear the analogue sources on your SPDIF out. HOWEVER. EPIA ain't using one of these.

    in addtion, for those sounds cards that does this, the analogue to digital conversion is done in a very noisy enviroment (on the board) hence noisy output is to be expected.

    Thanks for your informitave response. Maybe you can point me in the direction of some sound cards that do do this or maybe a USB device that has some line ins.

    I am looking for an answer to a problem. My problem is that I need to get a LINE IN (for my radio) to play out the digital port.

    What do I need to do to accomplish this?

    Is there any sort of USB recording device that would enable me to hook up an exteral source that would plug into my computer via USB and convert the Analog to Digital.

    And are you saying that the CD IN is not digital?

    before i start, could you tell me how you intend to use your digital SPDIF?

    if the final destination of the SPDIF is a digital pre-amp, most of these can accomdate analogue signal mixing as well.

    if your final destination is that of a digital amp (which as far as i know, there is only one, and i don't think it's even on market) then you are stuck.

    the only soundcard that i have experience with that can digitise analogue line in to SPDIF are onboard soundcards on Gigabyte motherboards. so i can't really help you there...

    perhaps you describe you intended setup and i see how i can help you

    and yeah.. CD-in is as analogue as it gets (the 4 pin connector). a few sound cards has digital CD-in, which is 2 pin (actually a SPDIF). anyway, most of the music softwares don't play CDs through the CD-in. they read it as CDA and play it via wave port.
