Why there is no sound when watching a video. What should I do if I slow down the sound when watching a video?

Watching movies on your computer is a favorite form of pastime for many users. Recently, for this very often used services like YouTube, but there are still a lot of those who prefer to view their favorite pictures with the help of familiar and functional media players. They are much more convenient, and the ability to change the format of the display, connect and disconnect subtitles, put bookmarks and labels is expensive.

Of course, when watching movies you can face some problems. For example, why is there no sound when watching a video? This misfortune often puts novice users at a dead end, but very often the problem can be solved with "little blood". On how to do this, read the article.

Something about stupid things ...

Do you think it often happens that users forget to turn on the speakers? And how often they can not connect them correctly to the corresponding connector on the motherboard or audio card? Alas, this happens very often.

So, carefully check the speaker connection, pay special attention to the integrity of the cable, as well as the correct connection of the plug to the line terminal to which the external signal is coming. If you insert the jack into the microphone jack, do not ask why there is no sound when watching the video.

As a rule, the speaker should be plugged into the green connector. If a digital output is used, then it is black. It is best to take instructions to your motherboard and study this issue in the most detail. With laptops, there is no such problem: green output - for speakers or headphones, and pink - for a microphone.

More serious reasons

So, you checked everything and checked everything, made sure of the integrity of the cable and the soundness of your sound equipment. Is there still no sound? Well, you have to "dig" deeper.

Most often (almost always) in the absence of a sound signal are the drivers are to blame. Of course, there are physical failures of "iron", but this happens very rarely. Considering that in most cases our users use motherboards with integrated audio controllers, when the latter fail, the whole motherboard is often "dropped", so it's hard not to notice.

Drivers

It so happened that the second in capriciousness (after the image) in the computer is the sound. And the reason for this are just the same drivers, the existence of which many users do not know at all.

If you still caught the times of XP, then for sure remember the wonderful codec AC97. The driver was firstly installed after the installation of the system itself. However, now also do not forget about the valuable experience of those days.

So, if you wondered why there is no sound when watching the video, first click the right mouse button on the "My Computer" icon (click on the "Properties" in the context menu), and then in the left part of the dialog that opens, select "Dispatcher Devices ". If there is an item "Sound, video ... devices", then everything is in order.

In the case when nothing like this is observed, and instead of the desired item there are several yellow exclamation marks, you will have to look for those same drivers. You can do this in several ways.

Put the drivers

First, you can try using the Windows Update service. You do this simply: click on the "Unknown Device" with the right mouse button (where the yellow exclamation mark), select the "Properties" item in the context menu. A dialog box opens in which you need to go to the "Driver" tab. Click the "Update" button.

In the next window, click the "Automatically search for drivers" button with the left mouse button. If you have a disk or a flash drive with the necessary files, click on the button "Run a search on this computer", and then specify the directory in which the searched drivers are located.

But why is there no sound when watching a video, even if all the audio devices are detected normally?

We put the codecs

Codecs are sets of programs designed to decode audio and video files. The best of them is considered to be the K-Lite Codec Pack. We recommend to install the Full version. You can download it on the official website.

The installation procedure is the simplest: first click the right mouse button on the installation file, and then select the "Run as administrator" item. A couple of times click on the "Next" button, on which the installation procedure can be considered finished.

Codecs must be set if there is a crack in the sound when watching a video. This symptom just shows that the system does not have built-in tools for decoding it.

Does the sound stop?

Alas, even the installation of such codecs is a 100% guarantee of success does not. The fact is that such programs are extremely "capricious". Experts generally recommend placing them exclusively on a "fresh" system, since otherwise problems with incompatibilities and internal conflicts can rarely be avoided.

So what do you do if you slow down the sound when watching a video? We recommend installing a player with a built-in codec set. Such programs practically do not conflict with the core of the system, and the speed of their work is often an order of magnitude higher than that of programs built into the OS. This is what allows them to process even massive MKV-containers, without "hanging" the system even on old computers.

The following utilities proved particularly useful: VLC, KMPlayer, GOM Player and Daum Player. It is strongly recommended to download them exclusively from the official website. As practice shows, there is no sound when watching video most often because of unsuitable codecs, so these programs in most cases allow successfully to solve such problems.

Online films

And again we return to the topic that was already touched at the beginning of the article. What can I do if the sound disappears when I watch a video in my browser ? There are two options: either you change the browser, or put a new Flash Player. However, it is best to perform both of these steps.

As for the new browser, experienced users almost unanimously say that the role of the "online cinema" is best suited browser Mozilla Firefox. It has the optimal characteristics, which allow you to enjoy the movie even in cases when a not very high-quality USB modem is used for communication with the network.
