Basic sound cards are still included in most computers
Most modern computers have a built-in sound card in the motherboard. Generating audio on computers is challenging because sound is fundamentally analog, while computers are digital devices. The human ear is incredibly sensitive to even the slightest changes in sound. The sound card's primary function is to convert digital signals into analog output for speakers and headphones, and vice versa for microphones.
Sound cards used to be expansion cards for early computers, often with ISA or PCI slots. However, as audio recording and playback became ubiquitous, and the cost of components decreased, it became common to incorporate basic sound card functionality into the motherboard. Although most computers no longer have physical sound cards, the term "sound card" still refers to the chips and functionality that provide audio output.
At the very least, a sound card provides a 3.5 mm stereo audio out and audio in TRS (tip, ring, sleeve) jack. Many modern devices now use a single 3.5 mm TRRS (tip, ring, ring, sleeve) jack that combines the headphone and microphone functions into a single port. Advanced sound cards offer additional input and output jacks for surround sound, digital outputs, or a digital optical audio port.
Sound cards are still included in most computers because integrated audio, while much improved, is not as good as dedicated hardware. For professionals, the difference is noticeable, and the dedicated hardware makes sense.

Sound cards convert digital signals to analog output
Most modern computers have a built-in sound card in the motherboard. This is because sound is fundamentally analog, while computers are digital devices. The sound card's primary function is to convert digital signals into analog output for speakers and headphones. This process is known as digital-to-analog conversion and is performed by a digital-to-analog converter (DAC).
A DAC converts a digital signal into an analog signal, and an analog-to-digital converter (ADC) performs the reverse function. Sound cards use both DACs and ADCs to convert digital signals to analog output and vice versa. This is because analog signals are continuous, while digital signals are discrete.
DACs are commonly used in music players, televisions, and mobile phones to convert digital data streams into analog audio or video signals. They are also used in modern communication systems to enable the generation of digitally defined transmission signals. The audio DAC is typically a low-frequency, high-resolution type, while the video DAC is a high-frequency, low- to medium-resolution type.
ADCs are integral to modern music reproduction technology and digital audio workstation-based sound recording. They are used to create pulse-code modulation (PCM) data streams for compact discs and digital music files. ADCs are also required in digital signal processing systems that process, store, or transport analog signals in digital form.
In summary, sound cards convert digital signals to analog output by using DACs and ADCs to convert digital data streams into analog audio or video signals. This allows computers to generate audio and connect to analog speakers, headphones, and microphones.
