Through the sound card.

General sound cards have a built-in playback function. If the sound card you use does not support multitasking, that is, stereo multiplexing, it means that you cannot play several sound files at the same time, and you cannot play MP3 in the chat room. It's like a sound song, but can play MIDI.

You can play music by turning on the stereo mix on the computer volume control console.
