I have a http://www.newegg.com/product/product.aspx?item=N82E16813153081&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-RSSDailyDeals-_-na-_-na&AID=10521304&PID=3818627&SID=
which says it has 6 channel audio, but there are not external plugs for the front, back, sub. So it sounds like just the chip supports it?
I want 5.1 sound for a CarPC and as you can see the chip is a low power slower chip so I don't want to use much if any CPU, but from what I can see all the USB 5.1 cards just convert from digital to analog audio and so all the audio processing is done on the CPU. Is this the case for all USB sound cards? Is it the case for all sound cards? Is there anyway to utilize the VIA VT1708A so the cpu isn't used.
Also anything I get I would like to be as low power as possible. If there is no way around a 5.1 usb soundcard using 5 +/- 0.25 volts (usb power only) then I could probably go up to 12 volts max.
Any suggestions, info or help would be great.
