In general, it depends on what you plan to do with your PC. If you’re simply using your computer for basic tasks such as browsing the web and watching videos, then a built-in sound card (integrated audio) should suffice.

However, if you’re an audiophile, a musician, or someone who requires high-quality audio for tasks such as audio production or gaming, then a dedicated sound card may be beneficial. Dedicated sound cards offer higher quality audio with better signal-to-noise ratio, lower distortion, and better amplification. They also typically have more advanced features such as noise cancellation, multiple output channels, and better compatibility with speakers and headphones.

Overall, whether or not you need a dedicated sound card depends on your personal needs and usage habits.
