How can I get the audio work?
1. Please confirm what output interface is the computer equipped with? (DVI? HDMI?) If your computer is equipped with DVI output, normally that the DVI output does not carry audio signals, so the audio signal cannot be output to the speaker.
2. After you connect the headset, you need to switch to the computer ith the audio device turned on. Only the computer that controls the audio playback will output audio.
3. If you have controlled the computer to turn on the audio device, select the correct audio output channel. (Right-click the speaker, open the sound settings, select the correct HDMI output device, and set it as default.)
