&#9744; Find the headphone jack; it is usually colored green or marked with a headphone symbol. &#9744; Find a pair of headphones or speakers from the shelf. &#9744; Run  or use an audio CD to test the jack output; mark your findings on the Keeper label. In laptops, we cannot physically replace the sound card, like we can in a desktop system. This limits our options when things go wrong. However, we can: System >> Preferences >> Sound, and click the Hardware tab. Click on the dropdown box by Profile. Select each hardware option in the menu one by one, and repeat the  test for each. At best, all audio outputs should work. &#9744; Note if speakers do not work, or are not present. &#9744; Note if the headphone jack does not work. &#9744; If both the internal speakers and the headphone jack are not working, check with your instructor.
