Is it possible to pass the output of one sound device to another?
I want to know this, because I have a USB Headset (Plantronics DSP 500) which installs as a new sound device and a SoundBlaster X-Fi ExtremeMusic and I want to use the Plantronics headset for gaming without having to abandon the rich features of the X-Fi. So I thought, maybe there is a way to pass the output of the
X-Fi to the Plantronics Headset sound device?!

It is but, I think it's not easily done in this case ... maybe then, if you
- have some additional inputs (analog/digital) in your headset or
- can find some software which can 'route' the X-Fi output to USB. There is this Virtual Audio Cable (VAC) but, does it work in this situation?

Actually, you propably could use some software for to input the X-Fi output and play it back through USB Headset. You need then route the output from X-Fi back (loopback cable from lineout to linein using either analog or digital path) and then use some recording software w/ Asio4All or VAC method (if this driver lists both audio devices) for routing. Also through some recording software (VSTHost, etc.) where you can use the Voxengo Recorder for to output to some MME device. Only bad issue you get by these rountings is the latency ... you hear all noises coming ~1 second delayed ... would that be nice?

Of course my headset does not have any inputs, that would be too easy
I rather thought of some software to route the sound virtually and not via line out/in. A delay would not be acceptable in my case, since I want to use it for gaming...

*UPDATE*
I found a tool named "Audio repeater" which comes with "Digital Audio Cable". It does what I want, but with a delay of at least 100 ms.
Do you think it is possible to find a solution that works without delay?

probably not, as they would all use WDM audio drivers, which unfortunately have a failr high inherent latency

How much that 100 ms is ? ... isn't that just 0.1 seconds. Maybe this is too long delay in gaming too (when you're fighting for your life) ... though, in audio creation work it's way toooo much (needs to be < 10 ms).

Does the 50 ms setting in Audio Repeater give audio issues? Also, did you try w/ different samplerate (22050Hz) and bit-depth (8) settings (arent game audio normally quite low quality?). I think lowering the bit-depth just lowers the volume level and setting samplerate to 22050 does not lower the audio quality at all (w/ that USB device) but does both devices work w/ these settings?

I tried every possible setting in this tool. 100 ms delay was the best possible result
