What can be offered for usb to optical(toslink) cable? I see some products on ebay, but i am not sure whats better to buy. I will use it to output from carpc with weak sound card with no optical out, to connect audison bit one, with optical in. The bit one have internal DAC, and i am not sure if i need usb DAC with optical out, or its better to have USB to Optical with no DAC if anybody can supply or give link to such product. I think i need just transport to the DSP, because it does not make sense to convert DA then AD then DA again ... maybe i just need to transport the Digital sound to the DSP, and then the dsp with the integrated DAC to finish its job. So what i am after is USB to Optical plain cable if such thing exist?
