So, if the sound does not work on the laptop, then you first need to diagnose the problem, determine why it happened, and fix it.
To get started, take a look at the tray icon (bottom right, around the clock). She will be in the form of a speaker. Opening it, you will see the sound settings panel. In it, all the channels of the device should be turned on, and the sliders are not set to the minimum (or better to the maximum) value. If this is all right, then go to the next item.
If your PC has several sound cards, then check if the exact device to which your speakers are connected is currently active. To do this, go to the "Control Panel" through the "Start" button. Select Sound, Speech, and Audio Devices, then Sounds and Audio Devices. In the "Audio" tab, in the "Default device" list, find the sound card you need.
Sometimes it happens that the sound does not work on the laptop due to the lack of codecs. Most often, with this cause of the problem, it appears only in the video files. At the same time,
system sounds (and audio, too) will function normally. Install codecs to fix the trouble. They can be found freely available on the Internet. They are installed by simply launching the file and clicking on the "Next" button.
When the sound does not work on the laptop, you should also check if the drivers for the sound card are installed. To do this, go to the "Properties" of the "My Computer" item, in the "Hardware" tab, click "Device Manager". And in the list of installed equipment you need to find your audio card (section "Sound, video and gaming devices"). If it is not, then the drivers are not installed on it.
To install software for a sound card, you need to visit the website of its manufacturer. There you should download the driver specifically for your version of the device. Installing it is similar to installing codecs.
When the
sound card software and another device conflict, the sound on the laptop also does not work. To check this, go to the "Device Manager" (how to do this, described above). If the sound card conflicts with another device, it will be marked with a red exclamation mark. If this is noticed, then you need to update its driver (how to do this, also described above).
And the last reason, because of which the sound does not work on a laptop or computer, may be a physically inoperative sound card or speakers. Try connecting headphones or other speakers to the PC. Make sure they are working. If there is sound in the connected speakers or headphones, then the
speakers on the laptop (those that are built into its case)
do not work , and the sound card is working. In this case, it is necessary to replace them in the service center. If there is no sound, most likely the sound card is faulty. Her replacement will cost more.
Since the headphones were mentioned, one more “problem” should be described, connected with them. This word is in quotation marks, because its reason is the carelessness of the user. When the headphones do not work on the laptop, and the speakers function normally, most often the problem is in the small volume control located on the wire, which is simply set to a minimum.
All the troubleshooting methods described above are suitable for both a laptop and a desktop computer. If they couldn’t return the sound to your computer, then it’s best not to take unnecessary actions so as not to aggravate the situation, and consult a specialist.
