What should I do if my computer's speakers, headphones, and audio devices have no sound ?, Speaker audio device
Computer speakers, headphones with no sound inserted. I have not changed to mute. Why is there no sound? How can I set up a playback device in Windows 7? If I check whether headphones and audios are correct. Let's take a look at how to set the playing device of the system.
If the taskbar's horn icon displays a cross or mute symbol, Enable volume adjustment. If not, click the small speaker icon.
Right-click the small horn icon (if you do not find it in the control panel-sound)-play the device.
If a black arrow icon is displayed on the playing sound device, the current device is disabled. Right-click the device and choose enable.
No device is displayed
If no device is displayed, select"Show disabled devices" "show disconnected devices"
After you select this option, you will be able to see the device. If not, click the device you want to configure and configure the speaker (if there are multiple devices, select the correct device and set it to the default device)
If the device has an exception, click test to enter the device speaker Test Wizard.
