<title>更改音量大小</title>

  <p>To change the sound volume, open the <gui xref="shell-introduction#yourname">system
  menu</gui> from the right side of the top bar and move the volume slider left
  or right. You can completely turn off sound by dragging the slider to the
  left.</p>

  <p>一些键盘有控制音量的按键，它们通常看着像发出声波的喇叭，常常在上边的“F”键附近。在笔记本键盘上，它们通常在“F”键上，按住 <key>Fn</key> 键，然后再按它们。</p>

  <p>If you have external speakers, you can also change the volume
  using the speakers' volume control. Some headphones have a
  volume control too.</p>

 <title>更改个别程序的音量大小</title>

  <p>You can change the volume for one application and leave the volume for
  others unchanged. This is useful if you are listening to music and browsing
  the web, for example. You might want to turn off the audio in the web browser
  so sounds from websites do not interrupt the music.</p>

  <p>Some applications have volume controls in their main windows. If your
  application has its volume control, use that to change the volume. If not:</p>

    <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">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>Go to the <gui>Applications</gui> tab and change the volume of the
      application listed there.</p>

  <note style="tip">
    <p>Only applications that are playing sounds are listed. If an
    application is playing sounds but is not listed, it might not support the
    feature that lets you control its volume in this way. In such case, you
    cannot change its volume.</p>
