diy usb audio with optical in / out
recently I got hold of a schematic of a diy usb audio device with optical ins and outs.. along with hardware volume and mute switch.. I want to built this thing, only needs like 20-30 components..
My question is.. since this thing has optical out, and my home dolby receiver has optical in.. will I be able to use this with the dvd player.. ?? I already know I can set windows that a dvd/cd player uses this usb for digital audio.. but will the 5.1 or dts signal put through ?
btw signal to noise of this diy is greater than 95 dB
Thanks in advance
