  <title>Dùng loa và tai nghe khác nhau</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 a 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. This socket is usually light green in color
  or is accompanied by a picture of headphones. Speakers or headphones
  plugged into a TRS socket are usually 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.</p>

  <p>Nếu bạn có loa hoặc tai nghe USB, hoặc tai nghe analog cắm vào cạc âm thanh USB, cắm vào cổng USB. Loa USB hoạt động như thiết bị âm thanh riêng biệt, bạn có thể xác định loa nào dùng làm mặc định.</p>
