No HDMI audio when graphics card connected to a Philips HDTV; How do I setup my NVIDIA based graphics card to work with my HDTV? If I am using a DVI-to-HDMI cable will audio be transmitted over this cable to the 3D TV? After installing a new Geforce graphics card with native HDMI audio or Displayport audio, my PCs onboard audio disappears. NVIDIA RTX Voice is a new plugin that leverages NVIDIA RTX GPUs and their AI capabilities to remove distracting background noise from your broadcasts, voice chats, and remote video conferencing meetings. Sometimes, when using my Nvidia cards, the HDMI audio option will magically disappear. This is how I usually solve the issue. Released earlier this month, RTX Voice uses the hardware found in Nvidia’s RTX GPUs to process your incoming and outgoing audio and eliminate almost all background noise.

RTX Voice is currently in beta. The tool allows users to 'go live' or join a meeting without having to worry about unwanted sounds like loud keyboard typing or other ambient noise in noisy environments. RTX Voice also suppresses background noise from players in loud environments, making incoming audio easier to understand.

Requirements

To use RTX Voice, you must be using an Nvidia GeForce or Quadro RTX graphics card, update to Driver 410.18 or newer, and be on Windows 10.

Running RTX Voice with GeForce GTX cards

Although RTX Voice is intended for RTX cards, with a simple hack you can install it on computers with other graphics cards. Download the installer and run it. If you don't have an RTX card you will get a message that says 'Nvidia Installer cannot continue.'

Not to worry, head to the directory where the files from the installer were extracted (C:tempNVRTXVoice) and look for a file named 'RTXVoice.nvi' (C:tempNVRTXVoiceNvAFXRTXVoice.nvi). Open the file with Notepad++ or other text editor and erase the following lines:

You must open the .nvi file as an Administrator to save changes. You can also edit permissions right-clicking on the file and selecting Properties > Security > Edit to Change Permissions. Once you have saved the changes, run the setup file again to complete the installation process.

Setup Guide

RTX Voice creates a virtual device on your system, and it is this virtual device that we want to use in your voice chat apps to denoise background noise from chat only, and not from your general Windows audio (as it would denoise unwanted audio feeds, like YouTube videos, Spotify music, or game audio).

To set it up:

• Download the App.
• Install it.
• Configure RTX Voice:
  • a. Select the microphone and speaker you want to use.
  • b. Turn on the background noise removal for the mic and/or the speakers.
• Configure your voice chat app according to the instructions below.

We recommend turning on RTX Voice for your microphone, and turn it on for your speakers only if needed. While quality remains almost the same, it is possible to see a small difference in some cases, and the solution takes system resources that you can avoid using if you don’t need it.

Discord

1. Go to Settings (cog wheel), and then select Voice and Video.
2. Select Microphone (NVIDIA RTX Voice) and Speaker (NVIDIA RTX Voice) as your devices.
3. For best quality, make sure that you disable any noise cancelling/removal effects in Discord.

OBS Studio

1. Go to Settings > Audio.
2. Select RTX Voice as your devices:
   • In Devices > Mic/Auxiliary Audio, select Microphone (NVIDIA RTX Voice).
   • In Advanced > Monitoring Device, select Speakers (NVIDIA RTX Voice).

XSplit

1. Go to Audio Settings.
2. Select RTX Voice as your devices:
   • Under System Sound, select Speakers (NVIDIA RTX Voice).
   • Under Microphone, select Microphone (NVIDIA RTX Voice).

Twitch Studio

1. Go to Settings, and navigate to Audio.
2. Select Microphone (NVIDIA RTX Voice) as your Primary Microphone.
3. For best quality, make sure that you disable the Noise Suppressor and Gate.

For best quality, make sure that you disable the Noise Suppressor and Gate.

WebEx

You can configure WebEx in 2 ways:

1. When you connect to the WebEx meeting you are asked how you want to connect to the meeting. Select Call Using Computer, and select NVIDIA RTX Voice for your devices.
2. When you are already connected, you can change your settings by going to Audio > Audio and Video Connections.
3. Select 'Change Settings'
4. Configure your device settings to use NVIDIA RTX Voice.

Zoom

1. Go to Settings > Audio Settings.
2. Select NVIDIA RTX Voice as your Speaker and Microphone device.

Slack

1. When you start a call, click on the settings icon on the top left.
2. Then configure NVIDIA RTX Voice as your device.

Skype

1. Click on Settings and go to Audio & Video.
2. Scroll down and change your Microphone and Speakers to NVIDIA RTX Voice.

Google Chrome

1. Go to Settings (3 dots on the top right, then Settings).
2. Click on Site Settings > Microphone.
3. Select Microphone (NVIDIA RTX Voice).

Applications can sometimes apply noise cancelling effects that will interact with one another. We recommend disabling the application’s settings if you are using RTX Voice, as well as any background noise removal in the software or driver that accompanies your microphone/headphones.

Test RTX Voice

To test the background noise removal, we recommend the following:

1. Setup RTX Voice (instructions above).
2. Select RTX Voice (Speakers) as your speakers in the Sound Settings of Windows (instructions above).
3. Open a video or recording with background noise (e.g. a YouTube video of an interview in the street). You can test the denoising by turning the background noise removal on and off on RTX Voice (Speaker path) and listening to the difference it makes to the audio.
4. When you finish testing, make sure you change back your speakers in Windows to your default! You will want to use RTX Voice as your speaker in voice apps, but not in Windows since you would filter audio that you don’t want to (like music, videos, etc.).

Note: RTX Voice Beta doesn’t control the volume of your underlying devices. If you are testing RTX Voice (Speakers) and want to adjust the volume, go back to your previous device, adjust the volume, and go back to RTX Voice.

To test your microphone, we recommend comparing the quality of your microphone with and without denoising. To do that:

Make sure that you have your microphone selected as your device in Windows. Click the Windows icon and search for Sound Settings, and select it in the microphone field.

1. Record your voice with your microphone.
   • Open an audio recording app, for example Window’s Voice Recorder. Click on the Windows icon and search for Voice Recorder.
   • Click on the record icon to generate a recording. We recommend reading the same text through the different texts while you have some background noise. Example text:

'RTX Greenscreen is a plugin that delivers real-time background removal of a webcam feed so streamers can replace their backdrop with different images or video. The plugin leverages AI to separate broadcasters from their background, adding to the professional quality of the stream and empowering users to take advantage of the benefits of a physical greenscreen without the expense and hassle of installation.'

Check that this test is capturing background noise. If your original audio doesn’t capture background noise, RTX Voice won’t be effective since it won’t have any background noise to remove.

1. Setup RTX Voice (instructions above).
2. Now record your voice using RTX Voice.
   • In the Windows Sound settings, select RTX Voice (Microphone) as your Microphone (see above).
   • Use Voice Recorder to record your voice reading the same text as before (see above).
3. Listen to both audio tracks with Voice Recorder or your favorite music application, and compare.

Earlier this month, Nvidia launched RTX Voice, a beta plugin that 'leverages NVIDIA RTX GPUs and their AI capabilities to remove distracting background noise from your broadcasts and voice chats,' as Nvidia put it in its announcement. But despite the 'RTX' branding, Ars testing confirms that the feature also works perfectly well on older GTX-level graphics cards. And despite that finding, Nvidia's installer refuses to allow the app on systems with non-RTX cards, unless the user performs some unintended config-file tinkering.

First, the good news: Nvidia's GTX Voice technology actually works really well. As you can hear in the test sample below, turning on the feature filters out almost all of the mechanical keyboard clicking picked up by a standard webcam microphone. That's likely to be an especially useful feature for anyone who has tried typing notes during a Zoom video call or dealt with kids screaming in other rooms during the same.

Now for the more questionable news: the 'RTX' in 'RTX Voice' seems to be a marketing misnomer. We know this only because of a workaround (seemingly first disclosed publicly by a Guru3D forum poster) that tricks the RTX Voice installer into working on a system with an older Nvidia graphics card. The process is as simple as running the installer, editing out a few lines from a temporary configuration file it creates, and then running the installer again without the 'constraint' check active.

Ars tested this method with an older gaming rig running a GTX 1060 video card. The successful results on that machine (which you can hear above) were indistinguishable from similar tests run on a more modern system with an RTX 2080.

What's more, the Windows system monitor only topped out at about 3-percent usage while actively running the RTX Voice noise cancellation on a GTX 1060. That suggests the older CUDA cores on the 1060 (and other older Nvidia cards) are more than enough to handle this feature and that the more advanced tensor cores in the RTX lineup aren't absolutely necessary for 'RTX Voice.'

More like “GTX Voice”

It's possible that older Nvidia GPUs may suffer more when running RTX Voice while the GPU is under heavy load from other video processing work. While the low GPU usage numbers in our test suggest any such impact won't be significant, we haven't performed comprehensive testing to substantiate this.

That said, it seems odd to completely bar non-RTX users from even trying out the beta on their systems (perhaps with an install-time warning) in order to judge the potential performance impact on their own. Over at Guru3D, users are reporting success running RTX Voice on Nvidia's 10XX and 16XX series cards, with more mixed results on the 9XX-series.

Nvidia was not able to respond to a request for comment as of press time (and we'll be sure to update if and when they do). But the company's announcement earlier this month suggested that the beta feature had been rolled out earlier than expected.

'Like many of you, we're all trying to adjust to our new normal. Our homes are now a shared office, streaming studio, and gaming den all in one,' staffer 'Tim@Nvidia' wrote. 'We've been silently working away on RTX Voice —our noise-cancelling app—but wanted to get this in your hands as soon as possible via an early-access community beta. The product is still in development, but we hope you find it useful!'

Development beta or not, for now it appears that limiting RTX Voice only to Nvidia's priciest graphics cards is a move that's being driven more by marketing than by any technical concerns. But Nvidia could still patch out this workaround at any moment, so if you want to RTX Voice on a GTX card, download the current beta build (V 0.5.12.6) as soon as you can.

[Update (April 24): Nvidia has provided Ars with the following official statement::

We posted an early beta of the RTX Voice app on our forums to get community feedback on performance and quality that would help us improve the final product. The interest is above and beyond our expectations. We appreciate all the feedback and will review it to help guide next steps.
