THX Spatial - Synapse is not making any sound through my Razer Nari Essential.

I have had this issue with these headphones for ages, even before I had to get them replaced on warranty. Basically, my issue is that whenever I set (THX Spatial - Synapse) as my default audio output in windows, I get no sound from applications that are sending sound to the default device. In Synapse under the mixer tab for these headphones, it says to set THX Spatial - Synapse as my default device for the best quality sound, but I don't get any sound. THX is enabled, and I can use things like the THX environmental and THX competitive game modes for virtual surround sound, but that only works when I have Razer Nari Essential set as my default speakers. Presumedly, I should be able to use these features in tandem to get a better experience, but the THX Spatial - Synapse audio device option has never worked for me in any capacity, and it allegedly should for these headphones as with all the ones in the Nari series. Please, if anyone can help me with this, let me know. I have tried reinstalling after wiping all data from the app's cache and all that, but nothing works.
