Hi,
 
I'm looking for a simple way to output stereo sound via a USB soundcard (on Windows) simultaneously to both a pair of active studio monitors and a HiFi amp. I don't want to upmix the sound or anything like that. However, usually in the sound panel in Windows you can only activate one output, as far as I know.
 
I was looking at the Asus U7, which comes with an extra Dolby software suite, but I can only find information about it's equalizer and surround functions.
 
Does anyone know if it's possible to use the U7 or another comparable USB soundcard to output the sound in general as stereo over two line outs?
 
Thanks!

You could do something where you route your audio through a VST host program and manually map each input channels to two output channels, but there really is no need to. A Y-splitter is a simple, cheap, fool proof solution designed for precisely your needs. It won't have any negative effect on the audio quality when used to connect a DAC to an amp, and in fact it will allow you to buy or use a single stereo output DAC which should be better quality and/or value than one with two outputs, so the resulting audio quality will actually be better.

To begin with there's only one pair of physical line output jacks. You can't get around that with software settings, hence the splitter.

 
Of course there are multiple line outs, it's a 7.1 soundcard after all.
 
I guess I'll just order it and see, and if necessary try the splitter work-around.
 
Thanks anyways for the replies!

Without using something like that Dolby program to "upmix" a stereo recording to 4ch or 5ch, you're stuck with splitters.
 
Besides why do you want to run everything at the same time when one set are active monitors and the other set are passives driven by a separate amplifier? You won't even get the same voicing on all speakers. If you weren't planning on running them at the same time then really the splitter is the best choice to begin with since you don't need to "upmix" at all, you just switch on whichever you want running.
 
Alternately you can use two different external converters - ie a DAC and a soundcard - hooked up to either speaker set. Then you just use Windows to manually switch which one you want.
