Wow, I found this program called HeSuVi which has a bunch of virtualization settings built in, it uses Equalizer APO which I already use to put a noise filter and noise gate onto my mic. Anyway, once I installed HeSuVi, I reconnected my USB Dolby Headphone adapter and was flipping the surround sound feature on and off, while toggling the HeSuVi program on and off. Using Dolby Home Theatre V4 Headphone, the sound between my USB adapters surround sound, and the HeSuVi surround sound is indistinguishable to my ears. Unfortunately, HeSuVi doesn't work at 384 sample rate, but it does work at 32 bits. So I could leave my audio device at 32/48, use HeSuVi, and get the surround sound effect I desire with the DAC.
