You shouldn't give up so easily.... There is software that will mirror your sound to different outputs, Oculus have a audio mirroring option, windows 10 offers this option for a lot of sound cards, there are many avenues for you to pursue if you don't, well.. give up and throw it in the cupboard.
VB-Audio's Voicemeeter Banana is the software I use to route the sound on my setup and whilst a bit fiddly to get setup, will do what you are trying to do.
It's Donate ware, so you can try it before making a contribution, if you wish.
