-'''Troubleshooting Audio'''<br>
-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.
