What is a key requirement for a home theater PC build regarding audio?

  1. Surround sound audio

  2. Mono audio

  3. Wireless headphones compatibility

  4. AM/FM radio tuner

The correct answer is: Surround sound audio

A key requirement for a home theater PC build regarding audio is surround sound audio. Surround sound allows for a more immersive audio experience, making you feel like you're right in the middle of the action. It is designed to replicate the sound distribution found in movie theaters and enhances the overall viewing experience. The other options are incorrect because - Mono audio only uses one speaker, which does not provide the same level of sound quality and depth as surround sound. - While wireless headphones compatibility may be a convenient feature, it is not a key requirement for a home theater PC build. It is more of a personal preference. - An AM/FM radio tuner is typically not needed for a home theater PC build, as it is primarily used for listening to radio broadcasts rather than enhancing audio for movies or TV shows.
