Apart from the generic solutions, we will also share a bonus tool that will make it easier to solve the NVIDIA HDMI sound not working problem.

Part 1: A Complete Overview of NVIDIA High-Definition Audio

It is a built-in audio driver that comes with NVIDIA GPUs to deliver sound output through HDMI connections. The driver allows users to transmit both video and audio signals through a single HDMI cable. This particular feature makes it a simple solution for home theaters, gaming setups, and presentations. Additionally, its ability to support HD audio formats on audio-capable devices ensures an immersive audio experience.

The driver also helps in relieving pressure from the CPU by taking the audio load on itself. Additionally, you can use it to stream multiple audio files on different devices simultaneously. Apart from its advantages, the driver can suffer from connectivity and problems related to the software. These issues often arise during system updates or when switching between multiple audio devices.

Part 2: What Can Be the Reasons Behind NVIDIA HDMI Audio Not Working

As said above, issues with this driver often arise from system misconfigurations or hardware faults. These problems are usually caused by incorrect default settings, outdated drivers, or cable failures. In this section, we will explore the most common reasons for NVIDIA HDMI audio not working problem:

1. Incorrect Audio Device: Sometimes, the HDMI output is not set as the primary audio source. As a result, the sound routes incorrectly from other sources.
2. Driver Problems: You can face this problem due to faulty or outdated drivers. Usually, when a driver gets corrupted, it can lead to compatibility issues and result in no audio output.
3. BIOS Settings: Some systems disable HDMI output in BIOS, which can block the sound transmission entirely.
4. Physical Damage: This issue can also arise if your HDMI port or the cable has a fault. When this issue occurs, it disrupts both video and audio signals between both devices.
5. Audio Settings Misconfiguration: Users can face this issue if the Windows settings are not properly configured.
