The use of sound cards has been a topic of discussion for PC users, especially those interested in audio quality. While modern motherboards have built-in speaker ports that provide adequate audio, sound cards can offer enhanced audio experiences. Sound cards are hardware devices installed in PCs to process and output audio. They are beneficial for music production or audio-focused work, providing various sound inputs and outputs like digital audio and surround sound. Sound cards also feature a DAC, which improves sound quality and minimizes electromagnetic interference. However, they may not be necessary for everyday gaming or basic sound output, as modern PCs often have good audio quality built into the motherboard. The decision to use a sound card depends on individual preferences and the specific use case for the PC.

What You'll Learn
Sound cards are not amplifiers
Sound cards are built into the majority of modern motherboards and will generally provide better audio than on-board sound ports. However, they are not amplifiers. The sound card on your computer does not have an amp built into it unless it is the headphone jack, and even then, it is normally 5W, which is not enough to drive passive speakers.
Sound cards are essentially equalizers and provide more choices for ports and in-depth software. They are not amplifiers and do not have the same function as amplifiers. Amplifiers take a line-level or DAC output and amplify it to 1500W or more, boosting the signal supplied by the sound card.
Some users may choose to use an amplifier with their sound card to improve sound quality, particularly for headphones. However, this does not mean that the sound card is an amplifier. The amplifier is a separate component that boosts the signal from the sound card.
In summary, sound cards are not amplifiers. They are audio sources that provide a signal that can be amplified by a separate amplifier component. The two components work together to provide improved sound quality, particularly for headphones or passive speakers.

Integrated sound controllers have made sound cards redundant
The integration of sound controllers into motherboards has contributed to the decline in the use of sound cards. Modern motherboards often feature built-in speaker ports, making external sound cards unnecessary for the average user. While sound cards can offer improved audio quality, they are not a mandatory component for basic functionality.
Sound cards used to be essential for audio processing and output on computers. However, with technological advancements, integrated sound controllers have become increasingly common. These integrated solutions provide adequate audio capabilities for most users, eliminating the need for dedicated sound cards.
The redundancy of sound cards is particularly evident in the context of modern gaming. Microsoft's adoption of OpenAL as the default audio interface for Windows Vista and later versions significantly enhanced audio compatibility for modern games. This shift away from proprietary interfaces, such as Creative's EAX, reduced the reliance on specific sound card models for proper audio fidelity.
Additionally, the integration of sound controllers offers advantages in terms of convenience and space efficiency. By eliminating the need for a separate sound card, system builders can streamline their setups and avoid potential compatibility issues. This is especially beneficial for compact form factors or when multiple expansion cards are involved.
However, it is worth noting that sound cards still have their niche. Professionals in the audio/music industry or enthusiasts seeking the highest audio quality may opt for external sound cards to minimize electromagnetic interference and achieve optimal sound output. Nonetheless, for the vast majority of casual users, integrated sound controllers have rendered sound cards an optional upgrade rather than a necessity.

Sound cards can be useful for music production
Sound cards can be beneficial for music production, offering several advantages over a computer's built-in audio capabilities.
Firstly, sound cards provide improved audio quality. They are equipped with specialised chips that excel at handling music, capturing nuances that a standard computer setup might overlook. This results in clearer, more professional-sounding recordings.
Secondly, sound cards offer expanded connectivity options. They accommodate multiple microphones and instruments, which is essential for music production, especially when recording ensembles or instruments that require numerous inputs, like a drum set.
Thirdly, sound cards address latency issues. Good sound cards significantly reduce the delay between playing and hearing the sound, ensuring a smoother and more seamless production experience. Cards like the RME Babyface Pro FS, for instance, boast super-low latency of just 0.8ms.
Additionally, sound cards can enhance signal fidelity. They often include a built-in DAC (Digital to Analog Converter) that amplifies the signal, ensuring it can be accurately reproduced by the speakers. A high-quality DAC provides a cleaner signal, which is crucial for music production.
For beginners and hobbyists, entry-level sound cards in the $100-200 range, such as the Focusrite Scarlett 2i2 or PreSonus AudioBox, offer excellent value and performance. More advanced producers might opt for mid-range or professional-grade cards with expanded features and superior sound quality.
While sound cards can be advantageous, they are not always necessary. Modern motherboards often have built-in speaker ports that may suffice for basic needs. However, for music production, a sound card can be a worthwhile investment, offering improved audio quality, expanded connectivity, reduced latency, and enhanced signal fidelity.

Sound cards can improve audio quality
Sound cards have higher-quality components than typical onboard audio solutions, resulting in clearer audio with an increased signal-to-noise ratio (SNR). They can be beneficial for certain use cases, such as legacy gaming or streaming with commentary, where enhanced audio quality can be advantageous. Additionally, sound cards with built-in amplifiers can be essential for powering high-impedance speakers or headphones, ensuring optimal performance.
For example, if you are using RAW audio or playing legacy games that require specific audio support, a sound card can make a noticeable difference. In these cases, investing in a sound card might be worthwhile. However, for streaming audio or video, the difference may be less pronounced due to compression.
The majority of modern motherboards have built-in speaker ports that are generally sufficient for most users. However, for those seeking a professional solution or wanting to minimize electromagnetic interference, external sound cards (or external DACs) are preferable.
It is worth noting that the effectiveness of a sound card also depends on the quality of the speakers or headphones being used. Higher-quality speakers often require a higher-quality amplifier and sound card to function at their full potential. Therefore, it is essential to match the impedance rating of your speakers or headphones with the appropriate amplifier and sound card.

Sound cards can be expensive
The cost of a sound card can vary, with some cards priced at around $150, while others can be as expensive as $1,000 or more. The price depends on various factors, including the quality of the AD converters, microphone pre-amplifiers, build quality, software, and drivers. Some sound cards also offer more inputs, which can be beneficial for those with multiple audio devices.
For those who are not satisfied with their current audio setup, investing in a sound card or an external DAC can be a way to improve the sound quality. However, it is important to note that simply buying an expensive sound card may not automatically improve the sound quality. The user's mixes, for example, need to be good or great to benefit from an expensive DAC interface. Additionally, if one does not need quality preamps and more inputs, a cheaper sound card may be sufficient.
For those with high-end audio gear or specific use cases, such as requiring extremely low latency audio output or optical outputs, investing in a more expensive sound card or external DAC can be worth the cost. However, for the average user, the built-in speaker ports on modern motherboards are usually sufficient, and a separate sound card is not necessary.
