Sound cards are no longer necessary for most users, as modern motherboards have built-in audio capabilities that are adequate for casual use. However, sound cards are still relevant for professionals or enthusiasts seeking high-quality audio, improved latency, or compatibility with legacy games and software. External digital-to-analog converters (DACs) have gained popularity as they offer similar functionality to sound cards, providing enhanced audio quality and minimizing electromagnetic interference. While sound cards are not as prevalent as they once were, they still exist and cater to specific use cases where dedicated audio hardware is required.

What You'll Learn

Sound cards are no longer necessary
Sound cards used to be essential for PC audio, but that is no longer the case. Motherboards have become increasingly feature-rich, centralizing components such as network cards, IO cards, and Wi-Fi cards. Basic versions of these components have become affordable, allowing consumers to buy external ones and move them between cheaper motherboards. This simplification is a significant advantage for consumers.
Internal sound cards are becoming obsolete for the average user. They are no longer a necessary buy for a PC, as the audio quality of onboard sound has improved dramatically. While a sound card might improve audio quality, it is not a significant enough upgrade for most users to justify the expense.
External sound cards (or external DACs) are preferred by professionals as they minimize electromagnetic interference by being external to the computer. They are also easier to connect to different computers, making them more flexible than internal sound cards. However, for most users, the onboard audio provided by their motherboard is more than sufficient.
While sound cards are still available, they are no longer necessary for most users. They are mainly focused on the pro/prosumer audio scene, offering extremely low latency audio output and other features that a motherboard might not have. However, for casual use, the default sound cards on modern motherboards are perfectly adequate, and there is no need to upgrade.

Onboard audio has improved
Today, onboard audio has benefited from a centralization of features onto the motherboard. Motherboards now often have their own audio chipset for processing, just like older sound cards did. This has improved the audio quality of onboard audio and reduced the need for a dedicated sound card.
The quality of onboard audio can vary depending on the size of the board, the number of PCB barriers, the amount of clutter, and the quality of filtering components. Larger boards with more PCB barriers, less clutter, and better filtering components tend to have better onboard audio. Additionally, advancements in technology have reduced the issue of audio interference, which was a common problem in the past.
For most casual users, the quality of onboard audio is good enough that they won't notice a significant difference between it and dedicated sound cards. However, for professionals or audiophiles, dedicated sound cards or external DACs may still be preferable as they can offer higher audio quality and minimize electromagnetic interference.
Overall, while onboard audio has improved, there are still some situations where a dedicated sound card or external DAC may be preferred or necessary, especially for users who require high-quality audio or extremely low latency.

External DACs are a popular alternative
External DACs (digital-to-analog converters) are a popular alternative to sound cards. They are easier to isolate and can provide an analog output like a sound card, but outside of the computer. They are also generally cheaper and easier to use with different computers over time, as most connect with a standard USB cable.
While sound cards are still relevant, particularly for professionals in audio production and reproduction, they are becoming less common for the average user. Motherboards have improved over time, with more features being integrated, and the quality of onboard audio has improved significantly. For most people, the quality of the onboard audio is sufficient, and they will not notice the difference.
However, for those seeking high-quality audio, an external DAC is a good option. They can provide improved audio quality, especially when paired with active speakers, and can be used to power high-end headsets, which motherboard audio often cannot.
Additionally, external DACs can help minimize electromagnetic interference by being external to the computer, and they often include integrated headphone amplifiers. They are also easier to upgrade than internal sound cards, as they can be used with multiple computers.
Overall, while sound cards are still relevant for specific use cases, external DACs offer a popular alternative that provides improved audio quality, ease of use, and flexibility for users seeking an upgrade from their onboard audio.

Sound cards are still useful for professionals
Sound cards are still a thing, but they are no longer necessary for most people. Onboard audio has improved significantly, and for the average user, it is usually enough to have a basic integrated circuit on the motherboard.
However, sound cards are still useful for professionals, particularly in the audio industry. For those who require high-quality audio, such as audio production/reproduction professionals, sound cards can provide a significant improvement over onboard audio. External sound cards, also known as external DACs (digital-to-analog converters), are often preferred as they minimize electromagnetic interference by being external to the computer. They can also provide more power to high-end headsets, which may not be possible with motherboard audio.
Sound cards can also be useful for gamers looking to upgrade their audio. While not necessary, a sound card can improve audio fidelity and provide a better gaming experience. Additionally, sound cards can offer extremely low latency audio output, which may be beneficial for specific applications.
For professionals who require specific audio inputs and outputs, sound cards can also provide extra features that motherboards may not have. For example, MIDI inputs and outputs, alternative connectors like optical audio, and additional microphone inputs.
While sound cards may not be necessary for the average user, they are still a viable option for professionals who require high-quality audio, low latency, and specific audio features.

Sound cards can improve audio quality
Sound cards are still relevant, especially for professionals or those who want to run a high-quality sound system. They are not a necessity for most people, as modern motherboards often have built-in speaker ports that suffice for everyday use. However, sound cards can indeed improve audio quality, and here's how:
Firstly, sound cards have higher-quality components, resulting in clearer audio output. The audio components are separated from the rest of the board, eliminating interference from other components. This separation ensures that there is no buzzing or other unwanted noise from your speakers, which can occur due to interference from certain video cards in specific slots.
Secondly, sound cards provide better audio than onboard sound, especially for those using high-end speakers or headphones. For instance, top-of-the-line headphones with an impedance of 300+ ohms require a sound card or amplifier of matching quality and output. Similarly, speakers with higher impedance ratings also demand a sound card and amplifier that can match their specifications.
Thirdly, sound cards offer improved audio fidelity, which is beneficial for recording and production. This is especially useful for activities such as streaming with commentary, where clear vocal recording is essential.
Lastly, sound cards can enhance audio cues in games, providing a more immersive gaming experience. They also support surround sound, with some cards offering 5.1 or 7.1 channels for a cinematic audio experience.
In conclusion, while sound cards may not be necessary for the average user, they can significantly improve audio quality for those seeking a high-fidelity sound experience, whether for gaming, music production, or simply enjoying audio with high-end equipment.
