As a Windows 10 user, you might have noticed your PC came equipped with Realtek High Definition audio drivers. While it is pre-installed on your PC, it doesn’t mean it is free of common errors.
Learning how to fix Realtek audio issues means first identifying the problem you have, then finding the right troubleshooting steps to correct it.
Sometimes it just takes downloading a new driver, while other times you might need a replacement for your sound card.
Before you assume it is one or the other, review these common errors and solutions.
The Most Common Realtek Audio Issues
Before offering troubleshooting advice, you first need to know the more common issues from Realtek’s audio drivers. These include:
- Missing Audio Manager Icon: After a recent Windows 10 update, you may notice your Realtek HD icon disappears from the taskbar. Typically, this comes from a driver issue.
- Conflicts with Preinstalled Microsoft Drivers: There are known issues between Microsoft system drivers and Realtek, which are an easy fix.
Why is Realtek High Definition Audio on My PC?
Realtek High Definition Audio Driver is the most popular sound driver for Windows systems, and it helps manage surround sound, Dolby and DTS sound systems on your computer.
You need this driver for your audio device to even work on the PC – so uninstalling it would create serious audio errors.
To further customize your sound experience, you can download the Realtek High Definition Audio Manager, but it is not necessary just to plug in new speakers or use your system’s sounds.
How to Fix Issues from Outdated Drivers or System Update Conflicts
If you recently updated your Windows 10, and your Realtek audio is nowhere to be found, the first troubleshooting step is to locate and update the driver.
1. Go Into Device Manager to Find Your Drivers
First, you need to identify the driver version you have for Realtek. Use your search icon on the Windows taskbar to look for your “Device Manager,” and select it.
Once the Device Manager is open, find your Sound, Video, and Game Controllers.
Expand the menu and see if your Realtek High Definition Audio driver exists.
2. Perform a Manual Update Push
Once you locate the Realtek HD Audio driver, right-click on that driver and select Update Driver.
You will then be prompted to Search automatically for updated software, or to browse for a manual driver located on your computer.
Select to search automatically.
Windows 10 will automatically begin updating to the latest driver available in their database.
3. Reboot Your PC
Now, do a full restart of your PC to save the changes.
You should see the Realtek High Definition Audio in the taskbar now if you click on your speaker icon to select an output.
If you still do not see the Realtek option in your speaker list, the next step is to see if Microsoft’s pre-installed drivers are causing the issue.
Disabling Microsoft UAA Bus Driver for High Definition Audio
Two high definition audio drivers never mix – and that goes for Realtek and Microsoft’s UAA Bus Driver.
If you haven’t done so before, you will want to disable this pre-installed driver.
1. Go Back into Device Manager
In Device Manager, scroll down to System Devices.
Look through the expanded list for Microsoft UAA Bus Driver for High Definition Audio. If it is not on the list, it was disabled already.
If you do see it in the list, you will need to disable it.
2. Disabling the Pre-Installed UAA Bus Driver
To disable, right-click on the Microsoft UAA Bus Driver for High Definition Audio and select Disable device.
3. Restart Your PC and Check for Further Issues
Do a complete restart on your PC for the disabled driver to take effect.
Then, see if your Realtek Audio shows in your list of outputs or if you get any further error messages.
Fix Realtek Audio Issues with a Rollback
If you recently updated and you see the version error compatibility message, then the next step would be to try a rollback of the most recently installed driver to the previous version.
1. Find Your Realtek Driver in Device Manager
Open the Device Manager and go to your Sound, Video and Game Controllers.
Expand the menu, locate your Realtek driver in the list, and right-click.
Select Properties.
2. Manually Rollback to Previous Versions
With the driver information up, click the Driver tab at the top of the menu.
Here you will see the driver provider, date of install, and version. Write down the version number on a piece of paper in case you need to reference it later.
Select the option to Roll Back Driver. Roll Back will take you to the previously installed driver, which is most likely the driver that was operating as it should before you did a Windows update.
If Roll Back is greyed out, then you have no previously installed version to roll back to. Click Roll Back Driver, then OK and follow the prompts to confirm the rollback.
3. Restart Your PC Again
Now, do another restart for the driver changes to take effect and see if that corrects the issue.
Use Automatic Recognition to Find the Right Driver
Often, Realtek HD audio drivers fail because they are out of date or you are using an incompatible version.
Instead of manually updating drivers and hoping for the best, you can take the guesswork out of the process by using Driver Support.
Upon installation it automatically inventories all drivers and software on your computer, and then searches for the most up-to-date drivers ready for installation.

Click Okay the installation.
2. Wait for the Initial Scan then Head to Drivers
Driver Support completes an initial scan of your system to inventory what drivers you have and any applicable updates.
Look under your Drivers menu and see if there are any warning icons next to your Realtek High Definition Audio drivers.
If you see a warning icon, it means your driver is out of date, and Driver Support has located the proper driver for you.
Click on that Driver, and then press Fix It! and Driver Support will automatically update the driver.
3. Restart Your Computer
As usual, you must restart your PC for any new drivers to take effect.
Once you have restarted, you should no longer see any issues with your Realtek High Definition Audio Manager.

Использование загрузочного диска/flash для проверки файловой системы на ошибки
Проверка LVM-разделов с помощью утилиты fsck
В определенных случаях (в результате сбоя или некорректного завершения работы) на файловой системе могут накапливаться ошибки. В РЕД ОС для проверки файловой системы и исправления ошибок имеется утилита fsck («file system consistency check»).
Инструмент fsck обладает следующим функционалом:
-
проверка файловой системы при возникновении проблем (не загружается система/поврежденные файлы) или в качестве профилактического обслуживания;
-
диагностика состояния внешних накопителей, таких как SD-карты или USB-накопители.
Базовый синтаксис соответствует следующему шаблону:
fsck <опции> <файловая_система>
В качестве файловой системы может быть устройство, точка монтирования или раздел, в том числе LVM.
Параметры fsck
fsck –p – утилита автоматически исправит найденные ошибки.
Вывод аналогичен простой проверке.
fsck –с – проверка файловой системы на поврежденные сектора.
Для получения списка команд наберите fsck ––help или fsck –h.
| Опция | Описание |
| -a | Устаревшая опция. Указывает исправлять все найденные ошибки без одобрения пользователя. |
| -r | Применяется для файловых систем ext. Указывает fsck спрашивать пользователя перед исправлением каждой ошибки |
| -n | Выполняет только проверку ФС, без исправления ошибок. Используется также для получения информации о ФС |
| -c | Применяется для файловых систем ext3/4. Помечает все повреждённые блоки для исключения последующей записи в них |
| -f | Принудительно проверяет ФС, даже если ФС исправна |
| -y | Автоматически подтверждает запросы к пользователю |
| -b | Задаёт адрес суперблока |
| -p | Автоматически исправлять найденные ошибки. Заменяет устаревшую опцию -a |
| -A | Проверяет все ФС |
| -С [<fd>] | Показывает статус выполнения. Здесь fd – дескриптор файла при отображении через графический интерфейс |
| -l | Блокирует устройство для исключительного доступа |
| -M | Запрещает проверять примонтированные ФС |
| -N | Показывает имитацию выполнения, без запуска реальной проверки |
| -P | Проверять вместе с корневой ФС |
| -R | Пропускает проверку корневой ФС. Может использоваться только совместно с опцией -A |
| -r [<fd>] | Выводит статистику для каждого проверенного устройства |
| -T | Не показывать заголовок при запуске |
| -t <тип> | Задаёт ФС для проверки. Можно задавать несколько ФС, перечисляя через запятую |
| -V | Выводит подробное описание выполняемых действий |
Пример проверки диска на ошибки с помощью fsck
Запуск автоматической проверки и исправления найденных ошибок
Существует несколько способов запуска автоматической проверки на ошибки:
1. Ручное добавление параметров в меню GRUB при загрузке ОС.
2. Добавление параметров в меню GRUB с помощью утилиты grubby.
3. Создание файла /forcefsck.
1. Ручное добавление параметров в меню GRUB при загрузке ОС
Первый вариант проверки и исправления ошибок на разделах жесткого диска.
В меню GRUB перейдите в режим редактирования загрузочной строки, нажав при этом клавишу e. Добавьте параметры:
fsck.mode=force fsck.repair=yes
в конец предпоследней строки.
Нажмите Ctrl+Х для запуска ОС с этими параметрами, во время запуска будет произведена проверка разделов диска, и при наличии ошибок произведено их исправление.
2. Добавление параметров в меню GRUB с помощью утилиты grubby
Существует еще один способ добавления параметров ядра для принудительной проверки файловой системы на ошибки и их исправления. Добавить параметры можно командой:
grubby --update-kernel /boot/vmlinuz-$(uname -r) --args="fsck.mode=force fsck.repair=yes"
Удалить установленные параметры можно следующей командой:
grubby --update-kernel /boot/vmlinuz-$(uname -r) --remove-args="fsck.mode=force fsck.repair=yes"
3. Создание файла /forcefsck
Бывают ситуации, когда систему необходимо проверить на наличие ошибок в незапланированный момент. Для этого можно принудительно запустить утилиту fsck для проверки при следующей перезагрузке. Запуск осуществляется командой:
sudo touch /forcefsck
Команда sudo (после ввода пароля) предоставит права для создания с помощью touch пустого файла в корне диска /forcefsck, который послужит сигналом (флагом) для fsck, что нужно проверить диски.
Останется только перезагрузить компьютер и fsck начнет проверять все жесткие диски, указанные в /etc/fstab.
Запуск проверки в ручном режиме
Следующий метод относится к проверке диска, когда операционная система загружена в режиме single mode.
1. Запустим ОС в single mode, для этого пропишите в меню загрузки grub параметр init=/bin/bash в конце строки, которая начинается на linux16, см. рисунок.
Также данная строка может начинаться с linuxefi, этот параметр характерен для систем с загрузкой в UEFI. Нажмите «ctrl+x» для запуска с этим параметром(init=/bin/bash).
2. Запустите проверку выполнив команду:
/usr/sbin/fsck -ACVfyv
Во время проверки на экране появится отчет о выполненных операциях, если отчет длинный, то можно его можно пролистать вверх сочетанием клавиш shift+PageUp. После проверки дисков перезагрузите компьютер, нажав на кнопку на системном блоке.
Наглядное видео примера проверки диска на ошибки:
Использование загрузочного диска/flash для проверки файловой системы на ошибки.
Загрузившись в режим восстановления операционной системы РЕД ОС с помощью загрузочного диска или съемного накопителя с установленным образом операционной системы РЕД ОС. Выберите пункт: «Решение проблем» -> «Исправить установленную RED OS».
Система перезагрузится в режим восстановления. Введите «2» и нажмите 2 раза Enter. Так вы смонтируете операционную систему в режим «Только для чтения»
Для корректного отображения в терминале кириллических символов введите команду:
setfont cyr-sun16
Потом введите команду:
# сhroot /mnt/sysimage
После этого можете вводить fsck:
# fsck -ACVfyv
Если проверка завершится с такой ошибкой:
[путь_к_файловой_системе] is mounted
Введите:
umount [путь_к_файловой_системе]
И еще раз запустите утилиту fsck:
# fsck -ACVfyv fsck from util-linux 2.30.2 …
Если система не выявит ошибок, то получится такой вывод:
[путь_к_файловой_системе] clean …
Чтобы выйти из режима восстановления, вы должны смонтировать все разделы, которые были отмонтированы командой umount, с помощью команды mount, нажать сочетание клавиш сtrl+d, а затем ввести команду reboot, которая перезапустит вашу операционную систему.
# reboot
По умолчанию, утилита fsck при проверке будет использовать разделы, указанные в /etc/fstab/, сформированные при установке операционной системы РЕД ОС.
Проверка LVM-разделов с помощью утилиты fsck
Перед проведением проверки необходимо найти устройство и размонтировать его.
Для просмотра всех подключенных устройств и проверки расположения диска выполните команду:
lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 0 20G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 19G 0 part ├─ro_redos-root 253:0 0 17G 0 lvm / └─ro_redos-swap 253:1 0 2G 0 lvm [SWAP] sr0 11:0 1 4,3G 0 rom /run/media/user/redos-MUROM-7.3.1 x86_64
При попытке запустить проверку на смонтированном диске или разделе в консоли появляется предупреждение о том, что невозможно продолжить проверку, так как диск смонтирован.
fsck -nf /dev/ro_redos/root fsck из util-linux 2.37.3 e2fsck 1.44.6 (5-Mar-2019) Warning! /dev/mapper/ro_redos-root is mounted.
Для того чтобы размонтировать диск, следует использовать команду:
umount <файловая_система>
Однако попытка выполнить данную процедуру на работающей ОС ни к чему не приведет.
umount /dev/ro_redos/root umount: /: target is busy.
Также проблемой при попытке проверить LVM-разделы может быть и то, что они являются не активными. Для проверки следует использовать команду:
lvscan ACTIVE '/dev/ro_redos/swap' [2,00 GiB] inherit ACTIVE '/dev/ro_redos/root' [<17,00 GiB] inherit
Для активации раздела служит команда:
vgchange –ay <раздел>
Таким образом, можно сделать вывод, что проверка LVM-разделов через консоль с использованием утилиты fsck невозможна. Но это не значит, что LVM-разделы совсем не подлежат проверке. Существует как минимум два способа, позволяющие провести диагностику LVM-разделов.
Первым способом является проведение проверки через консоль загрузчика операционной системы GRUB.
А вторым — запуск утилиты fsck в live-сессии системы.
Очевидным плюсом при проверке дисковых пространств, в том числе LVM-разделов, через live-сессию является то, что разделы там по умолчанию являются не смонтированными. Поэтому проверка LVM-раздела будет выполнена с первого раза.
