Each PC user faced problems with a sound on the Internet, probably. At someone the sound does not work on the new computer, the software or the operating system, at someone everything perfectly functioned earlier, but in one wonderful morning in columns the silence came. But in most cases the sound vanishes for quite natural reasons, and it is possible to restore it.
First, check operability of your columns or earphones. Cases when contacts depart are frequent or simply the cat of a wire peregryzat. Connect them to any audiodevice with the suitable connector, whether it be a player or the cell phone, and check sounding. If in that case it is absent, then, most likely, columns should be sent either to repair, or to a wastebasket.
Secondly, check availability of the updated and installed drivers of the sound card. For this purpose right-click on the My Computer icon - Properties – the Equipment – the Device manager. If icons of audio devices have yellow exclamation marks, then come into properties and follow instructions for reinstallation of the driver. If in the Device manager breakdowns are not displayed, then open the Control panel – Sounds and audiodevices and look for input-output devices. If they are not displayed, then install the driver manually from a disk or download from the Internet. The model of the sound card can also be learned in the Device manager.
If earlier the sound worked, but suddenly disappeared, then you, perhaps, caught a virus on open spaces of a world wide web and it is necessary to get rid of it as soon as possible. Download Kaspersky Internet Security 2012 from the official site, install on the PC and activate a trial version for 30 days. Configure the antivirus scanner under the needs and start full check of a system.
Quite often problems with a sound are solved by simple reinstallation of audio- and video codecs. The most popular and free set of codecs is K-Lite Codec Pack. Download upgraded version and install over old. If you just connected the Internet on the new computer or the operating system, then it must be done first of all, without codecs neither the sound nor video will normally not work.
And if sounds it is not heard only during the work in the browser, then update Flash Player or install it if it was not made earlier. The majority of Internet players work at Flash technology and without player do not function. Pay attention that different programs for editing audiofiles or management of a sound on PCs which are displaced in a tray can behave it is uncontrollable in network. Therefore disconnect them and check a sound. Most often there is enough standard mixer from Microsoft, other programs only load a system.
