They can be used to reduce electrical interference
Most modern computers have onboard sound cards, which are also known as integrated audio. These are usually more than enough for the average user. However, for professionals or audiophiles, a dedicated sound card can be a worthwhile investment.
Sound cards can be used to reduce electrical interference. Interference is usually caused by an internal grounding problem on the motherboard or a ground feedback loop. A sound card can help to shield internal components and create distance from the noisiest parts of your PC, improving audio quality.
Sound cards that sit outside the computer case, such as certain PCI sound cards, are less likely to experience interference as they are further away from the internal components that cause electromagnetic interference. Additionally, interference only affects analogue signals, so if the sound card outputs a digital signal, it will not be affected by electromagnetic noise.
If you are experiencing electrical interference, there are some troubleshooting steps you can take before investing in a sound card. These include ensuring your speakers are plugged into the same circuit as your computer and unplugging everything else from that power bar.

They can be beneficial if your motherboard doesn't support audio features like surround sound
Modern PCs have good audio quality built into the motherboard. However, if your motherboard does not support audio features like surround sound, installing a sound card can be beneficial.
Sound cards are pieces of hardware installed inside a PC to output and process audio. They can improve audio clarity and provide more audio interfaces than onboard audio from the motherboard. They are especially useful for audiophiles who want to connect multiple high-end speakers, microphones, or headphones to their PC. The extra ports on a sound card can support immersive gaming experiences, and the sound card's software tools allow users to tweak audio settings with surround sound simulators, equalisers, and noise reduction filters.
For example, if you are a collector of FLAC or lossless audio files and your current setup doesn't support native sample rates or bit depth, a sound card can help achieve optimal audio quality. Additionally, sound cards can shield internal components from interference caused by other PC parts, improving audio quality.
However, it's important to note that many mid- to high-end motherboards have well-isolated built-in sound cards, so a dedicated external or internal sound card may not be necessary. Motherboard audio has improved significantly over the years, and for everyday gaming or basic sound output, a sound card is not required. Instead, investing in better PC components or high-quality headphones/speakers may be a better option.

They can be replaced by external DACs
Sound cards are internal hardware installed inside a computer to process and output audio. They contain a Digital-to-Analog Converter (DAC), which converts digital audio information into audible analog sound. While sound cards used to be popular in the early days of modern personal computers, they have since declined in popularity due to the emergence of external DACs, which offer several advantages.
Firstly, external DACs offer convenience and versatility. Unlike internal sound cards that require plugging into the motherboard inside the computer, external DACs can simply be placed on your desk or an accessible location. This avoids the hassle of opening up your computer and dealing with internal connections. Additionally, external DACs can be easily moved between devices, providing portability.
Another advantage of external DACs is their ability to reduce noise interference. In internal sound cards, the analogue signal travels inside the computer case, where it can be susceptible to electrical noise from various components. External DACs, on the other hand, receive the digital audio signal directly, bypassing the internal components and reducing the opportunity for noise. While DACs can still introduce their own noise if not properly engineered, they generally offer a theoretical advantage in terms of noise reduction.
For audiophiles and professionals, external DACs can provide improved sound quality. While most modern PCs have built-in DACs, external DACs can offer higher-fidelity sound and support for high-end audio equipment. Additionally, external DACs often come with additional features, such as an amplifier (amp) or an analog-to-digital converter (ADC), providing further flexibility for musicians, podcasters, and streamers.
It is worth noting that sound cards may still be relevant for gamers who prioritize audio immersion and lossless audio file playback. Sound cards can shield internal components from noise and provide dedicated software-based audio processing tools, such as equalisers and surround sound simulators. However, for most users, an external DAC is a more practical and accessible option, offering cleaner sound and easier connectivity.
