<title>Non podo escoitar ningún son do computador</title>

  <p>If you cannot hear any sounds on your computer, for example when you try
  to play music, try these troubleshooting steps to see if you can fix the
  problem.</p>

<section id="mute">
  <title>Asegúrese que o son non está desactivado</title>

  <p>Open the <gui xref="shell-terminology">system menu</gui> from the right
  side of the top bar and make sure that the sound is not muted or turned right
  down.</p>

  <p>Algúns equipos portátiles teñen interruptores de silencio ou teclas nos seus teclados, probe a premer dita tecla para ver se se activa o son.</p>

  <p>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. Also, open <app>Settings</app> from the <gui>Activities</gui> overview
  and click <gui>Sound</gui>. Go to the <gui>Applications</gui> tab and check
  that your application is not muted.</p>

</section>

<section id="speakers">
 <title>Comprobe que os altoparlantes están acendidos e están conectados correctamente</title>
 <p>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.</p>

 <p>Algunhas tarxetas de son son capaces de cambiar o zócalo que usan para a saída (dos altoparlantes) e a entrada (desde o micrófono, por exemplo) e a entrada (desde o micrófono, por exemplo). O zócalo de saída pode ser diferente cando se executa Linux no lugar de Windows ou Mac OS. Tente conectar o cable do altavoz aos diferentes zócalos de audio no equipo sucesivamente, para ver se funciona.</p>

 <p>Unha última cousa que comprobar é que o cable de son estea conectado correctamente na parte traseira dos altoparlantes. Algúns altoparlantes teñen máis dunha entrada.</p>
</section>

<section id="device">
  <title>Comprobe que o dispositivo de son correcto está seleccionado</title>

  <p>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.</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-terminology">Activities</gui> overview and
      start typing <gui>Sound</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Sound</gui> to open the panel.</p>
    </item>
    <item>
      <p>In the <gui>Output</gui> tab. Make a note of which device and which
      profile are selected (so you can return to the default selections if
      changing them does not work).</p>
    </item>
    <item>
      <p>Para o dispositivo seleccionado, tentar cambiar o perfil; reproducir un son despois de cambiar o perfil, para comprobar que funciona. Pode necesitar ir a través da lista e probar cada perfil.</p>
    </item>
    <item>
      <p>If that does not work, you might want to try doing the same for any
      other devices that are listed.</p>
    </item>
  </steps>

<section id="hardware-detected">

 <title>Comprobe que a tarxeta de son foi detectada correctamente</title>

  <p>Your sound card may not have been detected properly. If this has happened,
  your computer will think that it is not able to play sound. A possible reason
  for the card not being detected properly is that the drivers for the card are
  not installed. You may need to manually install the drivers for the card.
  How you do this will depend on the card you have.</p>

  <p>You can see what sound card you have by using the <cmd>lspci</cmd> command
  in the Terminal. Go to the <gui>Activities</gui> overview and open a Terminal.
  You may have to run <cmd>lspci</cmd> as
  <link xref="user-admin-explain">superuser</link>; either type
  <cmd>sudo lspci</cmd> and type your password, or type <cmd>su</cmd>, enter
  the <em>root</em> (administrative) password, then type <cmd>lspci</cmd>. See
  if an <em>audio controller</em> or <em>audio device</em> is listed—it should
  have the make and model number of the sound card. <cmd>lspci -v</cmd> will
  show a list with more detailed information.</p>

  <p>You may be able to find and install drivers for your card. It is best to
  ask on support forums (or otherwise) for your Linux distribution for
  instructions.</p>

  <p>If you cannot get drivers for your sound card, you might prefer to buy a
  new sound card. You can get sound cards that can be installed inside the
  computer and external USB sound cards.</p>
