There are usually too many cables to worry about when connecting video and audio between many devices. If you connect a computer to an HDTV display, the entire system looks disorganized without proper cable management. However, graphics cards that feature NVIDIA High Definition Audio can solve this issue!
NVIDIA High Definition Audio conveniently channels audio to an HDMI connection without extra cables. Graphics cards with this feature work as a sound controller by integrating an audio card with internal codecs. It supports multi-channel 5.1 audio and 16-24 bit sample sizes but does not support analog devices, like headphones and speakers connected to the computer.
What is NVIDIA High Definition Audio?
NVIDIA High Definition Audio uses internal codecs on a GPU-integrated audio card to provide high-quality sounds on an HDMI connection. As a result, you do not require audio cables when connecting a computer to an HDTV.
NVIDIA digital audio is better than analog audio because all data transfers between devices. It also supports compressed multi-channel 5.1 audio better than the Sony/Philips Digital Interface.
However, the codec is incompatible with analog audio used by headphones and speakers. It does support audio within 32-192 kHz, 16-24 bit sample sizes, and stereo or 7.1 speaker setups. Additionally, you can listen to multiple audio channels and Blu-Ray audio formats.
Computers with a GT212 GPU or newer include NVIDIA HD Audio. It is also compatible with Linux and Windows XP to 10.
NVIDIA HD Audio vs Realtek HD Audio
Sound quality depends on connected audio equipment and audio bitrate, so comparing NVIDIA and Realtek HD Audio is challenging. Both deliver excellent sound quality, with different computer configurations and user needs.
NVIDIA High-Definition Audio routes digital audio from your computer to an HDMI output, whereas Realtek High-Definition Audio handles analog audio on a motherboard sound card.
Realtek High-Definition Audio
Realtek HD Audio provides a user-friendly way to detect headphones, speakers, and microphones on a computer. After installing its drivers, you can enjoy analog sounds and configure detailed audio settings.
It outputs stunning audio, but quality depends on the integrated or dedicated Realtek sound card. Newer motherboards with solid capacitors typically have great sound cards, but dedicated sound cards deliver studio-quality audio. Regardless of your sound card, you need to update your motherboard and audio drivers to the latest version to avoid issues.
The audio quality may also degrade if you have a small form factor system, such as a miniature HTPC, due to the headphone cable on the front. Some cables are also closer to internet components, making an induction screeching noise. As a result, Realtek HD Audio may not be best for cases without shielding.
NVIDIA High-Definition Audio
Unlike Realtek, NVIDIA HD Audio does not support analog audio. Instead, it uses internal codecs to process audio to an HDMI output without third-party cables. It also includes an integrated control panel to optimize 1080p displays so you can conveniently watch Blu-Ray movies on an external display. If you want to use headphones or speakers, you need to use a different built-in PC sound controller.
Do not use cables longer than 12 feet, and update your drivers to the latest version to avoid issues. You should also avoid using a KVM, audio receiver, or HDMI switch because it can worsen audio quality.
