Что делать если в компьютере пропал звук: [Есть решение] Пропал звук на компьютере или ноутбуке

Пропал звук на компьютере (windows XP/7/8/8.1/10). Решение проблемыИсчезновение звука на компьютере – неприятная, но вполне решаемая проблема. Ознакомившись с нижеизложенной информацией, вы узнаете, почему может пропасть звук на компьютере и что делать в подобных ситуациях.

Проблемы с аппаратным подключением

В первую очередь проверьте правильность аппаратного подключения колонок. Рекомендация в особенности актуальна для семей с детьми и животными, которые могут случайно выдернуть штекер. Убедитесь, что колонки подключены, штекер «сидит» плотно и не болтается.

Проверьте, в правильное ли гнездо вставлен штекер. Как правило, гнездо для колонок имеет светло-зеленый цвет, для микрофона – розовый, для записи с внешней аппаратуры – синий. Диаметр каждого из этих выходов равен 3,5 мм, т.е. вставить по ошибке штекер в соседнее гнездо несложно, но звук, конечно же, при этом работать не будет.

Проблемы с колонками

Штекер на месте? Убедитесь в исправности колонок. Для этого подключите их к любому другому устройству, способному воспроизводить музыку. Как вариант, можете подключить к компьютеру любые другие наушники или колонки вместо «замолкшей» аппаратуры.

Проблемы с уровнем громкости

Банальная, но довольно распространенная причина, встречающаяся преимущественно у неопытных пользователей. Обратите внимание на состояние соответствующей иконки. Кликните по ней и задайте подходящую громкость.

Проблемы с драйверами

Убедившись в отсутствии аппаратных проблем, проверьте компьютер на наличие программных сбоев, прежде всего, в отношении драйверов. При отсутствии драйверов или возникновении разного рода проблем с ними, иконка настроек звука будет иметь такой вид. Кликните на значок.

Откроется меню устранения проблем.

Установите динамики по умолчанию (если компьютер укомплектован внешними колонками) и кликните «Далее».

Немного подождав, пока система выполнит требуемые действия, кликните «Применить это исправление».

Система оповещает об успешном устранении проблемы. Закройте оповещение и проверьте звук.

Ситуация, когда упомянутые драйвера отсутствуют в составе операционной системы по умолчанию, встречаются преимущественно, когда компьютер укомплектован редкой звуковой картой от малоизвестного производителя. В данном случае драйвера придется установить самостоятельно, воспользовавшись диском из комплекта, специальной программой для автоматического поиска драйверов либо же зайдя на сайт производителя оборудования.

Проблемы с настройками BIOS

Звук может пропасть по причине отключения встроенной звуковой карты в BIOS. Для проверки нужно зайти в BIOS (на стационарных компьютерах он, как правило, запускается с помощью клавиши Delete спустя пару секунд после нажатия кнопки включения) и в разделе «Advanced» либо «Integrated» (может меняться в зависимости от версии БИОС) проверить состояние параметра «High Definition Audio». Ваша задача – выставить этот параметр в положение Enable.

Проблемы со службой Windows Audio

Компьютер может «молчать» по причине пребывания упомянутой службы в деактивированном состоянии. В Панели управления либо через Поиск находим раздел Администрирование.

В категории «Службы» находим Windows Audio. Хорошо, если она настроена на автоматический запуск.

В противном случае надо дважды нажать по строке службы Windows Audio и настроить ее на автоматический тип запуска. Выставив необходимые параметры, кликаем Применить.

Восстановление звука через службу устранения неполадок

Можете попробовать избавиться от возникших проблем при помощи универсального диагностического средства. Находим раздел «Устранение неполадок» через Панель управления либо через Поиск (в зависимости от версии ОС и личных предпочтений).

Кликаем на соответствующую ссылку.

Жмем Далее.

Система пытается обнаружить проблемы.

Спустя некоторое время служба расскажет об итогах изучения состояния системы. В рассматриваемом примере звук пропал по причине убавления громкости. Для решения достаточно попросту выставить громкость на требуемый уровень.

Проблемы со звуковой картой

Если вышеприведенные методы не позволили избавиться от проблемы, с большой долей вероятности все дело непосредственно в звуковой карте. В такой ситуации не останется другого выхода, кроме как купить отдельно устанавливающуюся звуковую карту или обратиться в ремонтный сервис с целью замены вышедшего из строя компонента.

Самый простой и удобный в установке вариант – это внешняя звуковая карта, подключаемая посредством USB-разъема. Установка такого компонента не требует от пользователя никаких особых навыков и избавляет от необходимости обращения в сервисный центр.

Своевременно реагируйте на возникающие проблемы, не паникуйте, действуйте в соответствии с проверенными рекомендациями и все обязательно получится. Удачи!

90000 Why do my computer speakers not work? 90001 90002 Updated: 06/30/2020 by Computer Hope 90003 90002 On this page, you’ll find information about what to do you if you are not getting any sound out of your computer speakers. The troubleshooting sections below should be followed in order because they help you identify your problem through the process of elimination. 90003 90006 Volume issues 90007 90002 If you are experiencing problems with the volume of your computer’s audio, following these steps may help you fix the problem.90003 90010 Desktop speakers turned down 90011 90002 This step may seem trivial, but problem-solving works best when you start with the basics. Verify that the volume knob on the speakers is turned up enough to produce a sound. Every pair of speakers with knobs increases the volume by turning it left to right, otherwise known as clockwise. 90003 90010 Laptop speakers turned down 90011 90002 If you are using a laptop computer with no external speakers connected, make sure the volume is turned up by using controls on the keyboard.The volume controls may be buttons (shown in picture), or a secondary function of another key indicated with blue text. To activate these keys hold the Fn key at the secondary function key at the same time. 90003 90010 Make sure volume of the software is also turned up 90011 90002 An important aspect of sound on a computer with external speakers is that it’s primarily controlled by software. For example, if the volume is lowered or off in the software settings, it will not matter how high the external speakers are turned up.The speakers will not produce sound. Therefore, users should verify the sound settings in the software are properly turned up. 90003 90010 Mute is on 90011 90002 Another common mistake is for the mute to be accidentally activated on the keyboard. To check if mute is turned on, look in the lower right side of the Taskbar for a symbol resembling a speaker with a «no» sign. 90003 90006 Speakers are not connected properly 90007 90002 Some audio problems may be caused by improperly connected speakers.To verify your speakers are connected correctly, follow these steps. 90003 90010 Laptop computers 90011 90002 If you are troubleshooting a laptop computer, skip this step since you can not verify the laptop speaker connections. 90003 90010 External desktop speakers 90011 90002 Sound devices connected to the computer have different cables and therefore use different ports. First, check the speaker cable connects to the sound card on the back of the computer. As seen in the picture, the sound card has multiple jacks.Speakers must be plugged into the Line Out connector, which is usually indicated by an image of sound waves with an arrow pointing out. The jack itself is usually green in color. If your speakers connect through USB, plug them into any of the USB ports. 90003 Tip 90002 Even if the speakers worked in the past, check the connection since it’s not uncommon for cables to become loose or be pulled out of place. 90003 90002 Ensure the power cable connects to the back of the right speaker, or in some cases, the subwoofer.Most speakers have a small LED (light) indicating if the speaker is on or off. Once you’ve turned the speakers on (usually by using a button or by moving the volume knob from left to right), look for a light. If no LED is visible, or the speakers still do not appear to be getting power, and you’ve checked the power connections, you may have a faulty power source. 90003 90006 Default playback device in Windows 90007 90002 If your computer has the Windows operating system, make sure the correct playback device is set as the default device for sound output.If the wrong playback device is set as the default device, the sound does not come out of the expected device (i.e., speakers or headphones). 90003 90046 90047 Open the Control Panel. 90048 90047 Click or double-click the 90050 Hardware and Sound 90051 or 90050 Sound 90051 icon. 90048 90047 In Windows XP and older, click 90050 Manage audio devices 90051 under 90058 Sound 90059. 90048 90047 In the Sound window, on the 90050 Playback 90051 tab, find the entry for the speakers connected to your computer.90048 90047 Right-click the speaker’s entry and select 90050 Set as Default Device 90051. 90048 90047 Click OK at the bottom of the Sound window to save the settings change. 90048 90071 90006 Windows speaker setup 90007 90002 If you are running Microsoft Windows, make sure the speaker setup is correct by following the steps below. 90003 90046 90047 Open the Control Panel. 90048 90047 Select 90050 Hardware and sound 90051 or 90050 Sound 90051 in the Control Panel window. 90048 90047 In Windows XP and older, click 90050 Manage audio devices 90051 under 90058 Sound 90059.90048 90047 On the 90050 Playback 90051 tab, select your speakers, and click the 90050 Configure 90051 button. 90048 90047 If the speakers still do not work after configuring and testing them, double-click the speakers on the Playback tab to bring up 90050 Speaker Properties 90051. 90048 90047 90050 Verify 90051 all settings and then 90050 Test 90051 on the 90050 Advanced 90051 tab. 90048 90047 After verifying all settings and making any changes, click 90050 Apply 90051 then 90050 OK 90051 in each of the appropriate windows before closing them.90048 90071 90006 Corrupt Windows system files 90007 90002 It is possible for Windows system files to become corrupted for any number of reasons. If system files responsible for sound output become corrupted, the computer can stop producing sound of any kind. 90003 90002 If the computer was producing sound recently but is not now, you can 90050 try restoring Windows to a previous point 90051 when sound was working. If corrupt Windows system files are causing the sound problem, restoring Windows to a point when the sound did work should resolve the issue.For more information, see: How to restore Windows to an earlier copy. 90003 Tip 90002 Make sure to back up your important documents before activating a Windows restore point. 90003 90006 Integrated or onboard audio disabled 90007 90002 If your computer has integrated or onboard audio, it’s possible it is disabled in the BIOS. Access the BIOS and find the entry for integrated audio. It may be located in a menu named something similar to 90058 Integrated Peripherals 90059 or 90058 Onboard Devices 90059, or it may be under the 90058 Advanced 90059 menu.90003 90002 After you have located the integrated audio entry, check if it’s set to 90058 Enabled 90059 or 90058 Disabled 90059. If set to 90058 Disabled 90059, change the setting to 90058 Enabled 90059. Restart the computer and test the sound. 90003 90006 Bad sound card 90007 90002 If the issue is not software related, it is likely a hardware issue. Like any other hardware component in a computer, the device producing sound can fail. Make sure the computer sound card works properly by connecting another pair of speakers or headphones to the computer.90003 Note 90002 Do not test the sound through a game or another program. Instead, see if a CD or a sound file works. A program or game may have sound-related problems that do not relate to the sound card. 90003 90002 If another pair of speakers or headphones also do not work, your sound card is likely experiencing issues. See the following page for troubleshooting help. 90003 90006 Bad speakers 90007 90002 Finally, if none of the recommendations above fix the problem, but connecting a different pair of speakers or headphones did work, the speakers are bad.We recommend you contact the manufacturer of the speakers or computer for a new replacement if they are still under warranty. Otherwise, you can buy a new pair of speakers and connect them to your computer. 90003 .90000 What can I do if my computer or laptop was stolen or lost? 90001 90002 Updated: 12/30/2019 by Computer Hope 90003 90004 Lost computer 90005 90002 If you lost a computer or laptop, the first thing you should do is retrace your steps to try and remember where you might have left it.

Generally speaking, there are two types of connectors used with microphones: the mini-plug and USB. Both types can connect to nearly any computer as most machines (including some laptops and Chromebooks) have both. To proceed, you can look at the images below to determine which type of connector your microphone uses and then follow the directions in that section.Or, if you know which connector your microphone utilizes, select the appropriate section from the list below and follow the instructions. 90003 90006 USB microphone 90007 90002 First, locate any available USB port and plug the microphone into it. Once connected, the computer should automatically detect the microphone and install the drivers for it. After the software is installed, you can verify the microphone is ready for use by accessing the sound settings and looking through the options.90003 90010 What if the mic is not detected automatically? 90011 90002 First, if you are plugging a USB microphone into the top or front of the computer try connecting it to the back of the computer. In some situations, it may only work if connected to the back of the computer. 90003 90002 If the computer still does not automatically detect your microphone and you’ve installed the software, you may need to download the drivers yourself. Fortunately, we have pages with these instructions, which are listed below: 90003 90006 Mini-plug microphone 90007 90002 Many microphones utilize a mini-plug connector, similar to that which you would find on your mobile phone, tablet, or iPod.On a desktop computer, the microphone jack is often located on the back and identified by the pink color, as seen in the image. However, microphone jacks may also be located on the top or front of the computer case. 90003 90002 Many laptop computers and Chromebooks have a microphone built into them. If not, the microphone jack is usually located on the front edge, or near the front left or right side. 90003 90010 What if the mic is not detected automatically? 90011 90002 If the computer does not automatically detect your microphone and install the software, you may need to download the drivers yourself.Fortunately, we have pages with these instructions, which are listed below: 90003 90006 How to see if the microphone is detected 90007 90028 90029 Open the Windows Control Panel, or press the Windows key, 90030 type Control Panel 90031, and then press 90030 Enter 90031. 90034 90029 Under 90036 Adjust your computer’s settings 90037, click 90030 Hardware and Sound 90031. 90034 90029 Click the 90030 Sound 90031 icon. 90034 90029 In the 90036 Sound settings 90037 window, click on the 90030 Recording 90031 tab to view the available microphones.90034 90029 Check if the microphone you plugged in is listed on the Recording tab and that it says 90030 Ready 90031 or 90030 Default Device 90031 underneath it. 90034 90057 Tip 90002 You can select the microphone in this list and click the 90030 Properties 90031 button to change microphone settings, including the volume level for recording. Click the 90030 OK 90031 button to save any changes to the settings. 90003 .90000 What to do about a stolen laptop 90001 90002 If you find yourself reading this article for any reason other than having had your laptop stolen, do yourself a huge favor and read this article about preventative steps for keeping your laptop (and the data on it ) safe from theft. 90003 90002 It’s always good to take steps that can help you avoid stress and anxiety. And a stolen laptop would cause that. 90003 90002 But if you reading this because you are indeed a victim of a stolen laptop or phone, we feel for you.90003 90002 Even if you escaped being physically harmed, there is a degree of violation that comes along with having such personal property stolen. 90003 90002 Here are six steps to act on as soon as possible in order to prevent even greater losses. 90003 90012 90013 1. GPS Location 90014 90015 90002 If you have not already, immediately check the built-in tracking system on your device to see the location of your device. Use whatever device you have not lost to search for the other, or if you’re stranded without a device at all, you might want to borrow a laptop from someone you trust.90003 90002 In the off chance you just left it behind, you can at least go check the area. (Of course, for your own safety, do not try to take matters into your own hands if it actually has been stolen and you find the culprit). 90003 90002 There are typically a few options that come with the built-in tracking systems: Sound, Lock and Erase. Once you have used GPS to track your device, you can click any one of these options and it will perform the chosen function. 90003 90002 If you’re in an area where the sound of the device could help you find it, try pressing «Sound» and listen for your laptop or phone to be making noise in the area it is located.90003 90002 A «Lock» function is helpful if you invested in a higher level of tracking-something such as LoJack for Laptops or a higher-level security device. There is an encouraging success rate from those who have invested in tracking software, so make sure to lock down your information immediately through that function and contact the company so they can begin their search. 90003 90012 90013 2. Wipe Your Data 90014 90015 90002 If you have little hope of recovering your computer, immediately using the «Erase» function to erase your computer’s data will be the most effective way to protect yourself from losing sensitive information to the thief.90003 90002 Some experts even recommend this extreme step-even if you happen to recover your laptop-just in case malware was installed on your computer that would still allow someone access to your information remotely. 90003 90002 If you have LoJack for Laptops, there is a function that allows you to erase specific sensitive documents … but sadly, there is no option to recover these later. 90003 90012 90013 3. Call Your Banks 90014 90015 90002 As soon as you realize your computer or phone is gone, contact your banks 90041 immediately 90042 to put freezes on your various credit and debit cards.Although access to your online accounts by the person who stole your computer is not automatically an outcome, you certainly do not want to take any changes with your money or investments. 90003 90002 More than that, you could have credit card information saved or on autofill on some of your favorite online shopping sites. If that’s the case, your payment source could be drained. 90003 90002 Your banks and other financial companies will be more than willing help you through the process of getting you new cards and monitoring your accounts.90003 90012 90013 4. Change Your Passwords 90014 90015 90002 If your computer has an autofill function when it comes to your passwords, a thief who knows or cracks your general computer password will now have access to the websites that have the most sensitive information about you. 90003 90002 Even if you think you might have a chance of recovering your computer, you will want to immediately log in to your accounts on a safe device and change your most sensitive passwords (90041 without 90042 updating autofill on all your devices, of course).90003 90002 These may include: 90003 90060 90012 banking sites 90015 90012 major shopping sites that you have an account with (like Amazon 90015 90012 other sites that would reveal sensitive information about you or give a thief the ability to make major purchases with your data. 90015 90067 90012 90013 5. Alert the Authorities 90014 90015 90002 Though the police will not launch a manhunt to track down the person who has your stolen laptop or phone, having a record of the theft and hopefully a serial number or IMEI (if you took it down before having the device stolen) will certainly help the police return any recovered property to the rightful owner.90003 90012 90013 6. Do follow up investigations. 90014 90015 90002 If your laptop is stolen, it will be important to monitor your credit and see if there is any suspicious activity. You can also keep tabs on local pawnshops or places like craigslist to see if anyone is se 90003.
