I’m trying to enable multiple off-the-shelf USB headphones/headsets on a PC to have the same desktop audio application stream to be fed to each and every headset. Also, if each headset has a mic, the mic audio signals should be mixed together in the software and be recordable in standard Windows software such as Sound Recorder.
Normally on a PC each connected USB headset is appended to a list of available sound devices and you can only pick one at a time to output audio to or get audio from the mic.
Is this doable for Windows XP, Vista, and Windows 7 ?
Thanks very much for your inputs.
No, it is not (regardless of how the audio device connects to the pc). Windows out of the box does not support streaming the same audio stream to multiple devices at the same time. I have personally asked the audio team for this feature …

Hi Doron,
Is it possible to create a custom driver to redirect the same audio stream to multiple devices simultaneously? Could you point me to the MS documentation (if any) about non-support of streaming audios to multiple device at the same time?
Thanks again.
BTW, I enjoy reading your A Hole In My Head blog very much:-)
I don’t think there are any public docs talking about a non feature. I don’t know enough about the audio infrastructure to know how to do this, but if you can create a default virtual audio device and then mux it to the real ones you could pull it off, but I have no idea if it is even feasible

have a look at VAC (http://software.muzychenko.net/eng/vac.html) this might
help you,
as Doron mentioned virtual audio device (MSVAD) can also help you out.
You can use xxxxx@freelists.org for audio related Questions.

You could certainly use something like Virtual Audio Cable as your
primary output device, have it route the data to an application, then
have that application reproduce the stream for each physical audio device.
However, my hunch is that it would be much quicker, much cheaper, much
easier, and much more reliable to do this job outside of the computer.
Just over $100 would get you a 1-in, 12-out audio distribution panel
that would do the job.

Thanks everyone. Also, not just audio outputs, if each USB headset has a mic, I want the mic audio input signals to be mixed together in the software and be recordable in standard Windows software such as Sound Recorder. Is this doable in Virtual Audio Cable?
Thanks.

With a separate application, sure, but again it would be much easier and
more flexible to get an external mixing board for this kind of thing.

If your question is “does VAC work in both directions” the answer is yes. You can define multiple audio cables with their own parameters and routing.
It’s a pretty good piece of software (though the most recent version – V4.10 – is reported to have some problems… I’d suggest you use V4.9 if V4.10 gives you any difficulties).
