Template:Laptop Audio Test

Requirements At best, all audio outputs should work.
 * Note if speakers do not work, or are not present.
 * Note if the headphone jack does not work.
 * If neither the internal speakers nor the headphone jack work, check with your instructor.

Test Internal Speakers and 1/8" Audio Jack &#9744; Open a Terminal and type &#9744; Find the headphone jack; it is usually colored green or marked with a headphone symbol. &#9744; Find a pair of headphones from the shelf. &#9744; Repeat the audio test or use an audio CD to test the jack output; mark your findings on the Keeper label.
 * You should hear an audio file play from both the right and left speakers.

Tip Use the same Terminal window and hit the up arrow to bring up a previously typed command, and then hit enter to repeat the command.

Troubleshooting Audio 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:
 * ensure that the sound card is recognized by the system by running.
 * double check that audio is not muted in the operating system. Click on the audio symbol in the top panel of the Desktop to check the volume settings.
 * run  in a terminal and check that volume levels for "Master" and "PCM" are set around 90.
