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
alsamixerin 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.
