# Non podo escoitar ningún son do computador

If you cannot hear any sounds on your computer, for example when you try to play music, go through the following troubleshooting tips.

# Asegúrese que o son non está desactivado

Open the system menu and make sure that the sound is not muted or turned down.

Some laptops have mute switches or keys on their keyboards — try pressing that key to see if it unmutes the sound.

You should also check that you have not muted the application that you are using to play sound (for example, your music player or movie player). The application may have a mute or volume button in its main window, so check that.

Tamén, pode comprobar a lapela de Aplicativos na interface de Son:

Open the Activities overview and start typing Sound.

Prema en Son para abrir o panel.

Baixo Niveis de volume, comprobe que o seu aplicativo non está en silencio.

# Comprobe que os altoparlantes están acendidos e están conectados correctamente

If your computer has external speakers, make sure that they are turned on and that the volume is turned up. Make sure that the speaker cable is securely plugged into the “output” audio socket on your computer. This socket is usually light green in color.

Some sound cards can switch between the socket they use for output (to the speakers) and the socket for input (from a microphone, for instance). The output socket may be different when running Linux, Windows or Mac OS. Try connecting the speaker cable to a different audio socket on your computer.

A final thing to check is that the audio cable is securely plugged into the back of the speakers. Some speakers have more than one input, too.

# Comprobe que o dispositivo de son correcto está seleccionado

Algúns equipos teñen varios «dispositivos de son» instalados. Algúns destes son capaces de facer saír o son e outros non, así que vostede debe comprobar que ten seleccionado o correcto. Isto podería implicar algún ensaio e erro para elixir o correcto.

Open the Activities overview and start typing Sound.

Prema en Son para abrir o panel.

Under Output, change the Profile settings for the selected device and play a sound to see if it works. You might need to go through the list and try each profile.

Se iso non funciona, pode tentar facer o mesmo con calquera dos dispositivos que se mostran.

# Comprobe que a tarxeta de son foi detectada correctamente

Se non se detecta a súa tarxeta de son, pode que os controladores da tarxeta non estean instalados. Pode que teña que instalalos manualmente. A forma de facelo dependerá da tarxeta que teña.

Execute a orde lspci no Terminal para obter máis información sobre a súa tarxeta de son:

Vaia á vista previa de Actividades e abra un terminal.

Run lspci as superuser; either type sudo lspci and type your password, or type su, enter the root (administrative) password, then type lspci.

Check if an audio controller or audio device is listed: in such case you should see the make and model number of the sound card. Also, lspci -v shows a list with more detailed information.

Pode que encontre e saiba instalar os controladores para a súa tarxeta. O mellor é pedir instrucións nos foros de soporte (ou similares) para a súa distribución de Linux.

Se non pode conseguir os controladores para a tarxeta de son, é posíbel que prefira comprar unha tarxeta de son nova. Pode obter tarxetas de son que se poden instalar no equipo e tarxetas de son externas USB.
