# 使用不同的音箱或耳机

You can use external speakers or headphones with your computer. Speakers usually either connect using a circular TRS (tip, ring, sleeve) plug or a USB.

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.

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.

如果您使用 USB 音箱或耳机，或者模拟信号耳机插入 USB 声卡，把它们插入任何一个 USB 接口。USB音箱将作为单独的音频设备，您可能要指定默认使用哪一个音箱。

# Select a default audio output device

Open the Activities overview and start typing Sound.

Click on Sound to open the panel.

In the Output section, select the device that you want to use.

Use the Test button to check that all speakers are working and are connected to the correct socket.
