Rerouting applications' audio to another audio device

Question

I have Virtual Audio Cables installed, but for some applications it's hard to have them permamnently rerouted through a different audio device, seen as they're missing a specific option to change this (Spotify or your web browser).

I'm wondering if it's possible to reroute another application's output audio-data to a different audio device (From my SPDIF to Realtek Digital Output, for example.), much like CheVolume can do.

Does anyone know if this is at all possible in C# (WinForms?)? And where would I start?
