  <title>Dùng microphone khác</title>

  <p>You can use an external microphone for chatting with friends, speaking
  with colleagues at work, making voice recordings, or using other multimedia 
  applications. Even if your computer has a built-in microphone or a webcam 
  with a microphone, a separate microphone usually provides better audio 
  quality.</p>

  <p>If your microphone has a circular plug, just plug it into the appropriate 
  adapter on your computer. Most computers have two adapters: one for 
  microphones and one for speakers. Look for a picture of a microphone next to 
  the adapter. Microphones plugged into the appropriate adapter will usually 
  be used by default. If not, see the instructions below for selecting a 
  default input device.</p>

  <p>Nếu bạn có microphone USB, cắm vào cổng USB. Microphone USB hoạt động như thiết bị âm thanh riêng biệt, bạn có thể xác định microphone nào dùng làm mặc định.</p>

  <steps>
    <title>Chọn đầu vào mặc định</title>
    <item><p>Nhấn chọn tên bạn trên thanh đỉnh và chọn <gui>Thiết lập hệ thống</gui>.</p></item>
    <item><p>Open <gui>Sound</gui> and select the <gui>Input</gui> tab.</p></item>
    <item><p>Select the device in the list of devices.
    The input level indicator should respond when you speak.</p></item>
  </steps>

  <p>If you don't see your device on the <gui>Input</gui> tab, check the
  <gui>Hardware</gui> tab. Make sure the profile for the device includes
  "input."</p>
