AS the board and CPU execute programs, they send associated sound signals to the sound card on your computer. The sound card converts the digital signal into analogue and sends that signal to the external port(s). Assuming a speaker is plugged in, the signal is carried over wire to the speaker (or headphone) speaker, where a electromagnet is used to move the speaker cone. This produces sound which can be heard.
Rather than using a USB sound card which can be awkward, I suggest that you go to Windows Help to try and sort out the problem as it is usually a software issue that is causing the distorted sound.
