Watching movies on a computer is a favorite form of pastime for many users. Recently, services like YouTube have been used very often for this, but there are still quite a few who prefer to view their favorite pictures using familiar and functional media players. They are much more convenient, and the ability to change the display format, connect and disconnect subtitles, set bookmarks and tags is worth a lot.
Of course, when watching movies, you may encounter some problems. For example, why is there no sound when watching a video? This misfortune often baffles novice users, but very often the problem can be solved with "little blood." Read how to do this in the article.
A little about nonsense ...
Do you think it often happens that users forget to include columns? But how often can they not correctly connect them to the corresponding connector on the motherboard or audio card? Alas, this happens all the time.
So carefully check the speaker connections, pay particular attention to the integrity of the cable, as well as the correct connection of the plug to the line output to which the external signal is being sent. If you insert the jack into the microphone jack, do not ask why there is no sound when watching a video.
As a rule, the speakers must be stuck in the green connector. If a digital output is used, then black. It is best to take instructions for your motherboard and study this issue in more detail. There is no such problem with laptops: a green output is for speakers or headphones, and a pink one is for a microphone.
More serious reasons
So, you checked and double-checked everything, made sure of the integrity of the cable and the serviceability of your sound equipment. Is there still no sound? Well, you have to "dig" deeper.
Most often (almost always) drivers are to blame for the lack of an audio signal . Of course, physical malfunctions of the hardware also happen, but this happens very rarely. Considering that in most cases our users use motherboards with integrated audio controllers, when the latter fail, the entire motherboard often “falls”, so this is hard to miss.
Drivers
It so happened that the second by capriciousness (after the image) in the computer is sound. And the reason for this is precisely the drivers, the existence of which many users do not know at all.
If you still found the time of XP, then you probably remember the wonderful AC97 codec. The driver was first installed on it after installing 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 a video, first right-click on the “My Computer” icon (click on “Properties” in the context menu, and then select “Dispatcher” in the left part of the dialog box that opens) devices. " If there is an item “Sound, video ... devices”, then everything is in order.
In the case when nothing of the kind is observed, and instead of the desired item there are several yellow exclamation points, you will have to look for the very drivers. This can be done in several ways.
We put drivers
First, you can try to use the Windows Update service. This is done simply: click on the "Unknown device" with the right mouse button (where the yellow exclamation point is), select the "Properties" item in the context menu. A dialog box opens in which you need to go to the "Driver" tab. Click on the “Update” button.
In the next window, left-click on the button “Automatic driver search”. If you have a disk or a flash drive with the necessary files, click on the button “Search on this computer”, and then indicate to the system the directory where the required drivers are located.
But why is there no sound when watching a video even when all audio devices are detected normally?
We put 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 installing the Full version. You can download it on the official website.
The installation procedure is simple: first click on the installation file with the right mouse button, and then select the option “Run as administrator”. A couple of times, click on the "Next" button, on which the installation procedure can be considered completed.
Codecs must be installed when the sound is cracking when watching a video. This symptom just indicates that the system does not have built-in tools for its decoding.
Does the sound slow down?
Alas, even the installation of this kind of codec does not give a 100% guarantee of success. The fact is that such programs are extremely "moody." Specialists generally recommend putting them exclusively on a “fresh” system, since otherwise it is rarely possible to avoid problems with incompatibility and internal conflicts.
So what to do if the sound slows down when watching a video? We recommend installing a player with a built-in set of codecs. 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 handle even massive MKV containers, without “hanging” the system even on older computers.
The following utilities have proven particularly good: VLC, KMPlayer, GOM Player, and Daum Player. We strongly recommend downloading them exclusively from the official site. As practice shows, there is no sound when watching a video most often because of inappropriate codecs, so these programs in most cases can successfully resolve this kind of problem.
Online films
And again we return to the topic that was already addressed at the beginning of the article. What to do if the sound disappears in the browser when watching a video ? There are two options: either you change the browser, or install the new Flash Player. However, it is best to complete both of these steps.
As for the new browser, experienced users almost unanimously say that the Mozilla Firefox browser is best suited as an “online movie theater”. It has optimal characteristics that allow you to enjoy the movie even when not using a very high-quality USB modem to communicate with the network.
