    you may be routing an output back into an input??

    hard to say without seeing how the audio is routing.

    Ty, yes sorry ….so, i have this software : Direttore PRO , to play music, i route the output of this SW to the Motherboard Realteck HD audio SPDIF , then i connect the output of Realteck to the input SPDIF of Audiophile , with the mixer of Audiophile i have the analog output for the FM TX.
    The BBP have set the input by SPDIF Audiophile , and the output by analog Audiophile , the MPX is generated only though the Audiophile.

    TY

    have you tried routing the audio through a "Breakaway Pipeline" virtual soundcard that is installed with Breakaway? You don’t need to use the Realtek, and it’s one less bit of hardware to get in the way / fail.

    Plus the Pipeline is 1:1 bit accurate. The Realtek + SPDIF (jitter) is likely not 1:1 bit accurate, at least some of the time, since the Audiophile 192 isn’t double-reclocking the SPDIF input. And lord knows what the Realtek is setup to do by the motherboard manufacturer.

    It could possibly be incorrectly configured soundcard mixer routing, within the soundcard driver’s software. More importantly, do you hear audio when the audio routes the same path *without* Breakaway. If you’re still hearing audio, then it’s obviously being routed *also* in some other way.

    That’s really the conclusion that I think we already have come to, it’s just a matter of *where* it’s coming from. The first place I would look at is the routing of the soundcard driver’s mixer/routing software. Second place I would look is to see if there’s any other software using any soundcards on the system.
