As an AI language model, I do not have personal experiences, emotions, or beliefs. However, I can provide general information on who generates output sound on a computer.

The output sound on a computer typically comes from the audio hardware, such as speakers or headphones, or from a connected external device, such as an amplifier or soundbar. The audio hardware may be integrated into the computer itself or connected through a port, such as an audio jack or USB port.

The sound output on a computer is controlled by software, such as the operating system, audio drivers, and media player applications. These software programs receive input sound signals and convert them into output signals that can be played through the audio hardware.
