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

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

Open the <gui xref="shell-introduction#yourname">system menu</gui> 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.

Also, you can check the <gui>Applications</gui> tab in the <gui>Sound</gui>
 GUI:

 <item>
 Click <gui>Sound</gui>.
 </item>
 <item>
 Go to the <gui>Applications</gui> tab and check that your application
 is not muted.

 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.

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

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.

<steps>
 <item>
 Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
 start typing <gui>Sound</gui>.
 </item>
 <item>
 Click on <gui>Sound</gui> to open the panel.
 </item>
 <item>
 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.

If that does not work, you might want to try doing the same for any
 other devices that are listed.

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.

Run the <cmd>lspci</cmd> command in the Terminal to find out what sound
 card you have:
 <steps>
 <item>
 <gui>কাৰ্য্যসমূহ</gui> অভাৰভিউত যাওক আৰু এটা টাৰ্মিনেল খোলক।
 </item>
 <item>
 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 root (administrative) password,
 then type <cmd>lspci</cmd>.
 </item>
 <item>
 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, <cmd>lspci -v</cmd> shows a list with more detailed information.
 </item>
 </steps>

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.

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.
