What's the difference between a digital sound card and an analog God card?

In fact, it can be understood as the output of digital signals and analog signals.

Our daily earphone speakers can only recognize analog signals, but analog signals are easily disturbed (obviously when a mobile phone is talking), and digital signals are not easily disturbed, but the speakers can't recognize them, so some traditional sound cards, including integrated sound cards, directly complete digital-to-analog conversion in the PC chassis, which is easy to be disturbed because there are many interferences in the chassis;

Therefore, some sound cards use direct digital signal output, such as fiber coaxial cable, to an external decoder. This decoder is actually equivalent to a traditional sound card, which is responsible for converting digital signals into analog signals for speaker recognition, but avoids the interference of Ned signals in the box. There is also a definition of digital sound card in the field of professional audio production, which can collect and generate digital audio signals.

Digital sound card means little to ordinary people. You can look at the computer's external sound card and think of it as UC30.
