DON'T select the 'Speakers (NVIDIA RTX Voice)' here. From the list of available devices, accessible by left-clicking the speaker icon in the system tray, select the playback device your headset is connected to. Next, you want to select your default playback device in Windows. That's basically it-you're done configuring the RTX Voice app. It will still filter the background noise of your own microphone. Just to clarify, if you keep this option off, the RTX Voice technology won't try to reduce the background noise from whoever you're talking to. As for the 'Remove background noise from incoming audio' option underneath the output device drop-down menu, NVIDIA recommends you keep it off, as activating it can result in some quality loss and increased system load. To hear the technology doing its magic to the fullest, it's best to leave these maxed out. The 'Noise Suppression' slider decides how much of the background noise will get filtered.

After you select them, make sure you check the 'Remove background noise from my microphone' option-only then does the RTX Voice technology actually kick in. As I have five or more different sound cards and microphones connected to my PC at any given time, my input and output device lists are somewhat crowded, but you shouldn't have much trouble finding your microphone and headphones.
