The problem I have is that I'm using Windows 7. and I need to be able to output audio from a PC to 2 devices simultaneously and have the inputs of both devices be valid recording devices.
However, I am using usb headsets (digital) so I can't use audio sound card channels.
I'm not sure but, if there some kind of software that can act as a virtual cable that can then output to multiple devices as well as receive from multiple inputs, that would be perfect. Or anything that can manipulate audio streams really.
What Ive looked into so far that I couldn't get to work:
Audicity (couldn't manage to output to 2 devices)
Virtual Audio Cable
VB Audio Cable (can't really use this anyway because of the licensing)
VB ASIO Bridge
USB Y-splitters (couldn't find any)
