"If a student or teacher were to contact me to help resolve a problem related to the audio output on their computer, the first thing I would check is whether the volume had been turned off. Once I confirm this, I would then go through a series of questions about whether the speakers were connected, if there is power to the audio components, and other connectivity issues. Finally, I would step the user through several different tests to determine where the problem is and how to resolve it. The final solution may require a recommendation to replace some of the audio components."
