'''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''' 
☐ Open a Terminal and type <code>speaker-test -t wav -c2 -l1</code>
*You should hear an audio file play from both the right and left speakers.
☐ Find the headphone jack; it is usually colored green or marked with a headphone symbol. 
☐ Find a pair of headphones from the shelf. 
☐ Repeat the audio test or use an audio CD to test the jack output; mark your findings on the Keeper label. 

<blockquote>
'''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 <code>lspci <nowiki>|</nowiki> grep -i audio</code>.
*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 <code>alsamixer</code> in a terminal and check that volume levels for "Master" and "PCM" are set around 90.
