☐ Find the headphone jack; it is usually colored green or marked with a headphone symbol.
☐ Find a pair of headphones or speakers from the shelf.
☐ Repeat the basiccheck audio test or use an audio CD to test the jack output; mark your findings on the Keeper label.
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 lspci | grep -i audio.
• 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 alsamixer in a terminal and check that volume levels for "Master" and "PCM" are set around 90.

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.
