What You'll Learn
Sound cards are unnecessary if you're using mid-range headphones
Sound cards are not necessary if you are using mid-range headphones, especially if you are not an audiophile. Onboard audio has improved over the years and is decent enough for most users. Most motherboards now come with good enough onboard sound, and the audio quality will depend on the setup you have and your level of interest in audio.
If you have easy-to-drive headphones, a sound card is not necessary, and it may only provide a minimal improvement in audio quality. Onboard sound should be sufficient for most users, and you can always upgrade to an external DAC/amp if needed. Sound cards are also unnecessary if your headset takes USB data input, as it already contains the DAC and amplifier chips found in sound cards and motherboards.
For those with harder-to-drive headphones, you may struggle to get enough volume from your motherboard's audio codec without sacrificing audio quality. In this case, a desktop headphone DAC/AMP may be a better option than a sound card, as it is not limited to use with your PC. Additionally, USB interfaces with XLR and phantom-powered mic-input, volume controls, and proper headphone amplification can provide a cost-effective alternative to sound cards, starting at around 30€.
If you are using mid-range headphones and are not an audiophile, a sound card is likely unnecessary. Onboard audio should suffice, and you can always consider upgrading to an external DAC/amp or USB interface if you feel the need for improved audio quality.

On-board audio is sufficient for most users
On-board audio, or built-in audio controllers, have improved significantly over the years and are now sufficient for most users. In the past, sound cards were necessary to improve audio processing capabilities and provide customisation options for sound settings. However, with advancements in technology, motherboards now come with high-quality audio components built-in, making sound cards less crucial.
Today's built-in audio controllers are more efficient and have a much lower impact on CPU resources. For most users, the on-board audio will meet their needs without requiring any additional hardware. It is worth noting that for specific use cases, such as complex photo and video editing or high-performance gaming, a discrete sound card can still be beneficial by offloading the audio processing from the CPU.
For gamers, the decision to use on-board audio or a discrete sound card depends on their setup and preferences. Modern gaming motherboards have built-in support for additional audio inputs and outputs, surround sound, and headphone jacks, which are suitable for most gaming setups. However, for gamers who want to optimise every component for the highest frame rates, a discrete sound card can be a worthwhile investment to offload audio processing and enhance the audio experience.
While on-board audio has improved, there are still situations where a sound card can provide benefits. Audiophiles who prioritise the best possible musical fidelity may prefer a discrete sound card to complement their quality speakers. Additionally, in rare cases where ultra-cheap computers lack audio output or have very low-quality integrated sound cards, an external sound card or DAC (digital-to-analog converter) and amplifier may be necessary to improve audio quality.
In conclusion, on-board audio has advanced to the point where it is sufficient for the majority of users. However, for specific use cases, such as complex media editing, high-performance gaming, or audiophiles seeking the ultimate audio experience, a discrete sound card or external DAC/amplifier can still offer advantages in terms of audio processing, customisation, and sound quality.

Sound cards are beneficial for audiophiles
Sound cards are particularly advantageous for audiophiles who require low latency and minimal interference. For instance, musicians who plug their instruments into their computers can benefit from sound cards that offer significantly lower latency than onboard audio. This ensures that they can play and monitor the output without experiencing any noticeable delay, which can be detrimental to performance and production.
Additionally, sound cards can provide a solution to interference issues. Onboard audio may pick up interference from other PC components, resulting in unwanted noise in the audio output. External sound cards, particularly those with USB interfaces, are isolated from internal case noise, be it electric or mechanical. This ensures a purer and cleaner sound, which is highly valued by audiophiles.
Moreover, sound cards offer a wider range of audio controls and enhancements. They often feature dedicated software that allows for granular control over audio settings, including equalization, surround sound, and environmental audio effects. This enables audiophiles to fine-tune their listening experience to match their preferences and the characteristics of their audio equipment.
While some may argue that external digital-to-analog converters (DACs) and amplifiers can provide similar benefits, sound cards offer an all-in-one solution. They combine the functionality of a DAC and an amplifier with additional audio processing capabilities, making them a versatile choice for audiophiles seeking to elevate their listening experience without investing in multiple separate components.
In conclusion, sound cards are beneficial for audiophiles as they offer improved sound quality, reduced latency, minimal interference, and enhanced audio controls. While onboard audio may suffice for casual listeners, sound cards provide the high-fidelity sound and advanced audio features sought by those passionate about audio excellence.

Sound cards can enhance the gaming experience
In the past, sound cards were a must-have for serious gamers looking to improve their audio experience. Sound cards typically had better audio processing capabilities and a wider range of customisation options than integrated sound. However, with advancements in technology, modern motherboards now have high-quality audio components built-in, and their software-based audio processing can rival that of high-end add-on cards.
Despite this, sound cards can still offer benefits for gamers. Firstly, they can utilise higher-end audio components, such as digital-to-analog converters (DACs), that provide higher bit rates and frequencies for higher-fidelity music and improved sound effects in games. Discrete sound cards can also achieve a higher signal-to-noise ratio (SNR) for a cleaner sound, free from the interference of other electronic components on the motherboard.
Additionally, sound cards can provide more connections, such as optical connections and higher-power amplifiers, accommodating higher-impedance headphones. Certain games with surround-sound modes can also benefit from sound cards, as not all integrated audio chips handle surround sound well, which can lead to flat or poorly staged sound.
For gamers with audiophile-level speakers or headphones, a sound card can be a worthwhile investment, providing the ultimate audio experience and allowing them to fully immerse themselves in the game. However, for the average or above-average gamer, a separate sound card is likely unnecessary, and the cost may outweigh the performance benefits.

Sound cards can offload audio processing
Sound cards are internal expansion cards that provide input and output of audio signals to and from a computer. They can also be external audio interfaces used for professional audio applications. Sound cards have evolved in terms of digital audio sampling rate, and some higher-end cards have introduced their own RAM and processor for user-definable sound samples and MIDI instruments.
Some sound cards, like the Sound Blaster series, have their own RAM and processor, which can offload audio processing from the CPU. This can free up resources for other tasks and improve overall system performance. However, the impact of audio processing on the CPU has not been a significant issue for several years, and modern CPUs are more than capable of handling audio processing.
Additionally, using an external DAC/amp with a sound card can further offload processing. This is because the external DAC/amp handles the conversion of the digital audio signal to an analog audio signal outside the computer case, reducing electrical noise interference. This setup can be beneficial for improving audio quality and reducing noise.
While sound cards can offload some audio processing, the benefit may be negligible in modern systems with powerful CPUs. For users with heavy CPU loads, certain sound cards like RME can provide a slight performance improvement. Ultimately, the decision to use a sound card depends on the specific use case and system configuration.
For example, a user with a laptop like a MacBook Pro may not be able to use a PCI sound card and may need to opt for an external audio interface or USB solution. On the other hand, a desktop user with a tower case can choose between internal and external sound cards, considering factors such as interference and desired audio quality.
