Is it possible to specify different inputs and outputs in JRiver?

I guess MC in windows does this by providing a pseudo sound driver.

In linux you can trivially create pseudo devices or "sinks" just by editing a config file and restarting.  Because "everythings a file" you can pipe in and out of such pseudo devices.  I'm not sure what it would take to be able to receive/monitor such data sources, but to be honest I'd be happy if MC could just accept a pipe; at that point it would be trivial to make a pulse sink that piped into MC.  Also there's actually already a loopback audio driver built into the ALSA tree (aloop).

I was somewhat aware of the devices alsa exposes as sources, at one time they showed up in the Audio Output configuration of MC and I filtered them out.
The thing I don't know much about is the how MC is stitched to the input. Will look into it when time permits...
