(apologies if this is off-topic for this forum - I looked around and this seemed the most appropriate!)
I have an audio interface / mixer (Zoom Livetrak L-8) with support for 2 independent stereo output channels from the connected computer (1-2 and 3-4). Its driver makes available both an ASIO and standard interface (not sure which exactly it supports but some of MME, WASAPI - the normal ones), and both can be used at once. However, given Windows' lack of (good) multi-channel audio support, the exposed non-ASIO interface goes to the first output channel (1-2).
What I would like to do is to be able to route some programs through the second output channel (3-4). This option is exposed in the ASIO device, but of course that is not accessible by most programs. So what I am looking for is something somewhat like virtual cable in how it exposes a standard audio device, but with ASIO-aware routing that can send incoming audio to specific ASIO channels. Does this exist, or is this use case just too niche?
Thanks!
p.s. Virtual cable isn't the best analogue, as I don't need its main feature of the virtual microphone - it's just the only program I know that exposes that sort of a virtual device.
