  <title>Use different speakers or headphones</title>

  <p>You can use external speakers or headphones with your computer. Speakers

  usually either connect using a circular TRS (<em>tip, ring, sleeve</em>) plug

  or with USB.</p>

  <p>If your speakers or headphones have a TRS plug, plug it into the appropriate

  socket on your computer. Most computers have two sockets: one for microphones

  and one for speakers. Look for a picture of headphones next to the socket.

  Speakers or headphones plugged into a TRS socket will usually be used by default.

  If not, see the instructions below for selecting the default device.</p>

  <p>Some computers support multi-channel output for surround sound. This usually

  uses multiple TRS jacks, which are often color-coded. If you are unsure which

  plugs go in which sockets, you can test the sound output in the sound settings.

  Click your name on the top bar and select <gui>System Settings</gui>, then click

  <gui>Sound</gui>. On the <gui>Hardware</gui> tab, select your speakers in the list

  of devices, then click <gui>Test Speakers</gui>. In the pop-up window, click the

  button for each speaker. Each button will speak its position only to the channel

  corresponding to that speaker.</p>

  <p>If you have USB speakers or headphones, or analog headphones plugged

  into a USB sound card, plug them into any USB port. USB speakers act as

  separate audio devices, and you may have to specify which speakers to

  use by default.</p>

  <steps>

  <gui>Hardware</gui> tab. Select your device and try different profiles.</p>
