If any one is interested, I ended up shutting off motherboard sound, pulling HDAV out and just using sound hardware on graphics card. I just don't see that any of that other sound hardware buys me anything I need. There isn't all the goofy DSP effect stuff like asus and realtek have built into their drivers but I don't want that stuff anyway. Still haven't figured out the time alignment with the PC thing but my Onkyo will do that so I guess I just have to do some stuff on the onkyo dsp.
The only not quite perfect thing I have come across is 192khz multichannel shared mode sample rate isn't working for me but 96khz 24 bit multichannel is.For all I know it's something wrong with the onkyo not ati's fault. Who knows?
