<title>I cannot hear any sounds on the computer</title>

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

<section id="mute">
  <title>Säkerställ att ljudvolymen inte är tyst</title>

  <p>Open the <gui xref="shell-introduction#yourname">system menu</gui> and make sure that
  the sound is not muted or turned down.</p>

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

  <p>Also, you can check the <gui>Applications</gui> tab in the <gui>Sound</gui>
  GUI:</p>
  <steps>
    <item>
    <p>Open <app>Settings</app> from the <gui>Activities</gui> overview.</p>
    </item>
    <item>
      <p>Click <gui>Sound</gui>.</p>
    </item>
    <item>
      <p>Go to the <gui>Applications</gui> tab and check that your application
      is not muted.</p>
    </item>
  </steps>

</section>

<section id="speakers">
  <title>Kontrollera att högtalarna är igång och korrekt anslutna</title>
  <p>Om din dator har externa högtalare, försäkra dig om att de är påslagna och att volymen är uppskruvad. Säkerställ att högtalarkabeln är ordentligt inkopplad i kontakten ”ljudutgång” på din dator. Denna kontakt är vanligtvis ljusgrön till färgen.</p>

  <p>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.</p>

 <p>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.</p>
</section>

<section id="device">
  <title>Check that the correct sound device is selected</title>

  <p>Some computers have multiple "sound devices" installed. Some of these are
  capable of outputting sound and some are not, so you should check that you
  have the correct sound device selected. This might involve some
  trial-and-error to choose the right one.</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Sound</gui>.</p>
    </item>
    <item>
      <p>Klicka på <gui>Ljud</gui> för att öppna panelen.</p>
    </item>
    <item>
      <p>In the <gui>Output</gui> tab, change the <gui>Profile</gui>
      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.</p>

      <p>Om det inte fungerar kan du behöva göra detsamma för de andra enheterna som är listade.</p>
    </item>
  </steps>

</section>

<section id="hardware-detected">

 <title>Kontrollera att ljudkortet detekterades ordentligt</title>

  <p>Your sound card may not have been detected properly probably because 
  the drivers for the card are not installed. You may need to install the drivers
  for the card manually. How you do this depends on the type of the card. </p>

  <p>Run the <cmd>lspci</cmd> command in the Terminal to find out what sound
  card you have:</p>
  <steps>
    <item>
      <p>Go to the <gui>Activities</gui> overview and open a Terminal.</p>
    </item>
    <item>
      <p>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>.</p>
    </item>
    <item>
      <p>Check if an <em>audio controller</em> or <em>audio device</em> is listed:
      in such case you should see the make and model number of the sound card. 
      Also, <cmd>lspci -v</cmd> shows a list with more detailed information.</p>
    </item>
  </steps>

  <p>Du kan nog hitta och installera drivrutinerna för ditt kort. Det är bäst att fråga efter instruktioner på supportforum (eller liknande) för din Linux-distribution.</p>

  <p>Om du inte kan få tag i drivrutiner för ditt ljudkort kanske du föredrar att köpa ett nytt ljudkort. Du kan köpa ljudkort som kan installeras inuti dator eller externa USB-ljudkort.</p>
