Why isn't my sound working on Ubuntu?

Answer 1

Some possibilities include:

* Your sound card isn't supported by ALSA. Check the ALSA website to see if your card is supported. * Your volume is turned down. * Your speakers are not turned on * Your sound card has been disabled in the BIOS.

Answer 2

Make sure that:

1. You have installed the driver for your sound card.

2. Your speakers are plugged into the correct jack, have power, and are turned up.

3. The sound mixer in Windows is turned up.

Answer 3

Although uncommon, it is possible that your sound card is not supported by ALSA (the set of drivers for sound cards in the kernel). Also make sure that you have turned up your volume in your mixer, including all bars.

Answer 4

When the sound isn't working on your Dell computer, the first thing you should check is the speakers. You will also need to go into the volume folder and make sure that the settings are correct.
