How is sound processed on a computer before reaching the speakers?

The sound card has no role in processing sound for the speakers.

The sound is directly sent to the speakers from the CPU.

When a sound is played on a computer, the CPU sends the digital data to the Digital Sound Processor on the computer's sound card. An on-board digital to analogue converter (DAC) then produces the analogue output that goes to the speakers.

A separate external sound processor is used to convert digital data to analogue for the speakers.
