Hey guys, want to thank you for posting this, working on Lenovo y510p, GTX 750m Edit: Not working after all, no sound/muting problem I ran into two problems, and corrected them. 1. Initialization Failed (no speaker/mic present?) In my case, I did not have anything show up in my Playback Devices under the Sound menu. Opening Device Manager, the NVIDIA RTX Voice Audio Device appeared under [Sound, Video, and Game Controllers] but said "Windows could not verify the digital signature... ..." Fix: I followed this guide to temporarily disable Driver Signature Enforcement https://www.wintips.org/how-to-fix-...s-file-error-in-windows-8-7-vista/#solution-2 Afterwards, the NVIDIA RTX Voice audio device appeared in my playback devices. This needs to be done every time you want to use RTX Voice. It is possible to permanently disable Driver Signature Enforcement, but the security risks are not worth it to me. 2. Unable to start microphone denoising As others have mentioned, this can be solved by updating the video card driver. Windows Update will NOT give you the latest driver. GeForce Experience will NOT give you the latest driver. Probably. Go here: https://www.geforce.com/drivers And use the MANUAL Driver search in order to find the latest version of your GPU drivers. In my case, I was able to update from v331 up to v421, but only by manually searching. Hope this helps, I made an account just to give back to the community. Great mod.
