All motherboards on the market come with embedded sound cards, also known as onboard audio. However, the sound quality of these built-in sound cards is not as good as that of dedicated sound cards due to space constraints. Dedicated sound cards offer improved features such as higher signal-to-noise ratios, lower harmonic distortion, and higher sample rates, resulting in better sound quality. For most users, the built-in audio on their motherboards is sufficient, but those seeking improved audio quality for music, gaming, or professional audio applications may benefit from investing in a dedicated sound card.

What You'll Learn
All motherboards have sound cards
Dedicated sound cards are typically purchased by those with specific requirements, such as those who require high-quality audio for professional voice acting or music recording. These cards can provide additional audio ports and improved sound quality, which may be necessary for certain activities like listening to lossless music on high-quality headphones.
For most general users, the integrated sound card in a motherboard is more than sufficient. It can power basic speakers, gaming headsets, and even a simple microphone. However, for those seeking an enhanced audio experience or pursuing specific audio-related tasks, investing in a dedicated sound card may be worth considering.
The decision to utilise the built-in sound card or opt for a dedicated one depends on individual needs and preferences. Some users may be satisfied with the integrated option, while others may seek the added benefits of a dedicated sound card, demonstrating the versatility of options available to modern computer users.

Dedicated sound cards improve audio quality
Motherboards do contain integrated sound cards, and for most general uses, this is enough. However, dedicated sound cards can improve audio quality, particularly for specific use cases.
Dedicated sound cards have higher-quality components, which means that audio will sound "clearer", with a noticeable increase in SNR (signal-to-noise ratio). This improvement in sound quality is due to the audio components being separated from the rest of the board, eliminating interference from other components. High-end motherboards with built-in sound cards often advertise this separation.
Additionally, sound cards often offer better headphone amplification stages and ostensibly better sound chips. For gamers, sound cards are a good option as they are built around gaming needs, such as surround sound. They also have their own processors, which handle all audio processing, freeing up the CPU to focus on other tasks such as improving frame rates.
For those with specific needs, such as voice actors, musicians, or video creators, a dedicated sound card can be a good investment. However, for the average user, the integrated sound card on a motherboard will usually be sufficient.

Integrated sound cards are fine for casual use
Motherboards do typically contain integrated sound cards, but whether or not you need a dedicated sound card depends on your requirements.
For casual use, an integrated sound card is fine. You can adjust the volume, switch between stereo and mono, and perform other basic tasks like plugging in a microphone for Zoom calls or casual podcasting. If you're a gamer, an integrated sound card will also suffice for general use with a basic speaker or a gaming headset.
Integrated audio chips are susceptible to interference from other components in your computer, which can cause a faint buzzing noise. They also rely on your CPU to handle sound processing, which can lead to a slight lag in more demanding tasks. However, if you don't notice any issues with the sound quality, there's no need to upgrade.
On the other hand, if you're an audiophile or a music producer, you may want to invest in a dedicated sound card. Sound cards deliver crystal-clear sound without interference and reduce the strain on your CPU. They also come with dedicated software that allows you to adjust EQ settings, create custom audio profiles, and simulate virtual surround sound.

Onboard audio has limited space
Onboard audio has improved significantly over the years, to the point where it is now sufficient for most PC users. However, for those seeking audiophile-level sound quality, a dedicated sound card may still be necessary.
One of the main limitations of onboard audio is the limited space available on the motherboard. Motherboards need to be small enough to fit into a tower, which restricts the size of the sound card. As a result, onboard sound cards cannot accommodate the same range of features as their dedicated counterparts, and the audio quality may not be as crisp or clear.
Dedicated sound cards, on the other hand, are standalone units with more space for additional technology. They can offer improved audio processing and higher-quality sound output, making them a popular choice for musicians, producers, audiophiles, audio editors, DJs, and professional gamers or streamers.
However, it is worth noting that dedicated sound cards also come with their own set of considerations. They require additional equipment, such as speakers or a headset, to truly appreciate the difference in audio quality. Moreover, they occupy one of the PCIe slots, which may be a concern with larger graphics cards.
Ultimately, the decision between onboard audio and a dedicated sound card depends on individual needs and requirements. For casual users or general use, onboard audio is typically sufficient. But for those seeking the highest level of audio fidelity or specific audio functionalities, investing in a dedicated sound card may be the more suitable option.

Discrete sound cards address interference
Modern motherboards have built-in audio controllers that offer sound quality that is good enough for most users. However, there are certain issues that can be addressed by using a discrete sound card.
Firstly, interference from other electronic components on the motherboard can cause a hissing sound, particularly when the audio is turned up but there are no active sounds being played. This can occur when data is being written to drives or when the CPU is under heavy load. A discrete sound card is not affected by this interference, and therefore users will not experience any unwanted noise.
Secondly, discrete sound cards can utilise higher-end audio components that are not available on motherboards. These can include digital-to-analog converters (DACs) that offer higher bit rates and frequencies for improved music quality and better sound effects in games. Discrete sound cards can also provide a higher signal-to-noise ratio (SNR) for a cleaner sound. For example, while the average built-in audio provides a 90 dB SNR, discrete sound cards can offer 106 dB or more.
Additionally, sound cards can provide more connections, such as optical connections, and higher-power amplifiers to drive higher-impedance headphones. For users who require specific connections that are not available on their PC's built-in audio, a discrete sound card can be a beneficial investment.
It is worth noting that HDMI is becoming the new standard for high-fidelity audio, reducing the need for sound cards. However, quality HDMI receivers can be expensive, and some users may still prefer to use a sound card for optimal audio quality.
