NVIDIA Virtual Audio is digitally signed by NVIDIA itself and is a verified product of the company. Usually, there has been no reports of any malware affecting it or disguising the module and infecting users’ computers.

On top of transmitting the volume for SHIELD, NVIDIA Virtual Audio is also used to communicate sound through the HDMI port present on your graphics card. There may be a perception of users that only video is transmitting through an HDMI cable. However, this is not true. As the technological world gets more advanced, HDMI is no exception and is one of the modules which has the capability to transmit sound on top of Video to any source.

An HDMI cable/port has two channels for transmitting i.e. Audio and Video. If you connect an HDMI to a projector or to another device which has an audio output, the audio will automatically be transmitted. This is similar to the case of connecting consoles to your TV; a single HDMI cable is used to transmit both Audio and Video.

If you do not have the virtual audio component installed on your computer, you will not be able to transmit the sound to the TV and only the video will be transmitted.
