No Sound In Windows 10 Or 11 After Update (Fix)

If you are a Windows 10 or Windows 11 user, you may experience issues with your sound after updating your system. If you are facing this issue, there is no need to worry as this problem can be fixed using the following steps.

The first and most obvious step in resolving the sound issue in Windows 10 and Windows 11 is to check your volume settings. It is possible that your volume is muted or set too low. Check the sound icon in the taskbar and make sure that the volume is turned up to an audible level. If you’re using external speakers or headphones, make sure they’re properly plugged in and powered on.

If the volume is not the issue, it’s time to check your playback settings. In some cases, the Windows update may have incorrectly selected the wrong playback device or disabled your device entirely.

In some cases, the Windows update may have incorrectly selected the wrong playback device or disabled your device entirely. Here’s how to check:

Select Sound. See also: How to Open The Old Advanced Sound Settings in Windows 11.

Go to Playback tab.

All audio playback devices connected to your computer will be listed in the Playback tab, including those in your monitor, graphics card, etc. You have to know which is the correct one that represents the speaker or headphones you want to use. If you don’t know, try to enable them one by one until the sound works.

If the playback devices tab shows “No audio device is installed“, go to the next solution.

Windows 10 and Windows 11 come with a built-in troubleshooter that can help diagnose and fix audio problems automatically. Here’s how to use it:

Go to Start Menu.

Search for “Troubleshoot” and open it.

Under Get up and running, select Playing Audio.

The process may take some time.

When the troubleshooting is completed, restart your computer. Play some music on YouTube to see if the no sound issue is resolved.

If your sound is still not working, it’s possible that your audio driver is outdated, corrupted, or incompatible with the latest Windows update. Here’s how to update your audio driver:

Go to Start menu. Search for device manager and open it.

Expand Sound, video and game controllers.

Select “Update automatically” to allow Windows to automatically find and install the correct audio driver for your device.

If it can’t find a suitable driver, you will need to manually install the driver by selecting it based on its model (usually we will install the Realtek High Definition audio). Check the post here and scroll to the bottom for detailed instructions on how to do it.

These are some of the solutions that can help you fix the no sound issue in Windows 10 and Windows 11. It’s essential to try each solution one by one until you find the one that works for you. It’s also crucial to ensure that your computer’s audio settings are correctly configured to avoid future sound problems.

If none of the solutions mentioned above works, you can try resetting your PC or contacting customer support for further assistance. Keep in mind that resetting your PC will remove all your installed applications and personal files, so make sure to back up your data before proceeding.

Usb Ports Are Not Working In Windows 11/10

In this article, we will talk about what you should do if USB ports are not working on your PC. USB ports on a computer allow users to connect different USB devices, like printers, keyboards, mice, etc. If the USB ports stop working, you will not be able to use any USB device. USB ports may stop working due to hardware and software issues.

USB ports are not working in Windows 11/10

A USB port stops working if it is faulty or if its drivers are outdated or corrupted. Sometimes, the latest Windows Update causes issues on a computer. In addition to the hardware and software issues, a USB port may also stop working if you quickly and repeatedly insert and remove a USB device. This article provides some helpful suggestions that you can follow if your USB ports are not working.

Power Cycle your computer

Check the power output of USB ports

Run Hardware and Devices Troubleshooter

Disable Fast Startup

Scan for Hardware Changes in the Device Manager

Roll Back, or reinstall USB Controllers

Change the Power Management settings

Uninstall and reinstall the USB Root Hub

Update your chipset driver

Disable the Selective Suspend feature of Windows

Uninstall the recent Windows Update

Restore your system

Perform an In-place Upgrade

Let’s see all these fixes in detail.

1] Power Cycle your computer

The first step that you should do is to power cycle your computer. The following steps will help you with that:

Turn off your PC.

Remove all the power cords. If you have a laptop, remove its battery after turning it off, and then remove all power cords.

Wait for a few minutes.

Laptop users can now insert the battery again.

Reconnect all the power cords.

Turn on your computer.

Now, check if the issue is fixed.

2] Check the power output of USB ports

Most USB ports supply 5V of electricity with a maximum current of 0.5 A. If your USB ports are working, they supply power output. If a USB port is not supplying power, it may be damaged. Check the power output of your USB ports to know if they are damaged or not.

If your USB ports are not supplying power, you need to take your computer to the service center.

3] Run Hardware and Devices Troubleshooter

The Hardware and Devices Troubleshooter helps Windows users fix hardware-related issues (if possible). In the previous step, if you find that your USB ports are not supplying power, run Hardware and Devices Troubleshooter before taking your laptop or desktop computer to the service center.

4] Disable Fast Startup

Fast Startup allows your computer to start faster than a normal startup. The Fast Startup does not completely shut down your computer. During the Fast Startup, the kernel session is not closed. Instead, it is hibernated. Windows does this by saving the kernel session and the device drivers (system information) to the hibernate file (hiberfil.sys). Due to this, sometimes, Fast Startup causes issues on a Windows computer. Check if the Fast Startup is enabled. If yes, disable it and restart your computer.

There are the following 4 ways to disable Fast Startup. You can use any of these methods.

The Control Panel

Command Prompt

Group Policy Editor (does not work on Windows 11/10 Home edition)

Registry Editor

5] Scan for Hardware Changes in the Device Manager

Some users have reported that the USB ports of their systems were delivering power but there was no connection. If this is the case with you, scan for hardware changes in the Device Manager. It will help.

Follow the steps written below:

Open the Device Manager.

The above action will help broken devices work again. Now, check if the issue is fixed.

6] Roll Back, or reinstall USB Controllers

A USB Controller manages the communication between a USB device and a computer. If the USB Controller gets corrupted, the USB ports may stop working. If the issue still persists, we suggest you roll back or reinstall the USB Controller driver.

Installing Windows Update also updates the device drivers (if an update for the same is available). If the issue started occurring after a Windows Update, it is possible that the USB Controller driver was also updated along with the Windows Update. In this case, the Roll Back option will be available in the Device Manager. Follow the steps below:

Open the Device Manager.

Expand the Universal Serial Bus controllers branch.

7] Change the Power Management settings

If you are still facing the problem, changing the Power Management settings of the USB Root HUB and USB Controllers will fix the issue. The steps for the same are written below:

Open the Device Manager.

Expand the Universal Serial Bus Controllers node.

Open the properties of USB Host Controllers and go to the Power Management tab.

Uncheck the “Allow the computer to turn off this device to save power” option.

Disable this option for all USB Controllers and USB Root Hubs in the Device Manager. When this option is enabled, Windows disables the USB devices after some time of inactivity to save power. When you use that device, Windows activates that USB device again. Sometimes, Windows fails to activate the device connected to a particular USB port due to which, it seems that the USB port has stopped working.

8] Uninstall and reinstall the USB Root Hub 9] Update your chipset driver

A chipset driver tells Windows how to communicate with the motherboard and small subsystems on it. One possible cause of this issue is the corrupted chipset driver. Update your chipset driver and see if it helps.

10] Disable Selective Suspend

Selective Suspend is a property by which Windows forces the connected USB device(s) to enter into a low power state. This happens when there is no bus activity on a particular USB port detected for some time. When you use your USB device, it starts working again. The purpose of Selective Suspend is to save power. If the above fixes did not resolve your issue, you need to disable the Selective Suspend feature. This action will affect all the USB host controllers and all the USB devices. After disabling Selective Suspend, all the USB devices continue to use power. Moreover, the “Allow the computer to turn off this device to save power” checkbox may be greyed out under the Power Management tab.

To disable Selective Suspend, you have to modify your Registry. Be careful while modifying the Registry, as any mistake can lead to serious errors in your system. Therefore, follow the steps explained below carefully and make sure that you modify or change the right registry key.

Before you proceed, we recommend you create a System Restore Point and backup your Registry.

11] Uninstall the recent Windows Update

If your system’s USB ports stopped working after installing a Windows Update, you can uninstall that update. Windows 10 users can uninstall Windows Update via the Control Panel. After Windows 11 2023 Update, it is not possible to uninstall the Windows Updates via the Control Panel. Hence, you have to use the Settings app for this purpose.

12] Restore your system

You can use the System Restore tool to take your system to the state before the issue started occurring. But this is only possible if a Restore Point was created. When you run the System Restore tool to restore your system, Windows shows you all the restore points created on your device along with the date. You can select any of these restore points. In your case, you have to select that restore point that was created before the issue started occurring.

13] Perform an In-place Upgrade

In-place Upgrade is the process of installing the Windows operating system over the existing Windows OS without uninstalling it. Using the In-place Upgrade, you can repair your system. Though an In-place Upgrade does not erase data, it will be good if you back up your data.

How do I get Windows 11 to recognize my USB device?

If Windows 11 is not recognizing your USB device, the first thing that you should do is restart your computer and see if it helps. In addition, the other things that you can do to get your USB ports to work again are running Hardware and Devices Troubleshooter, disabling Fast Startup, rolling back or reinstalling the USB Controllers, updating the chipset driver, disabling the Selective Suspend feature, etc. In this article, we have explained some working solutions to fix this problem.

Why do my USB ports suddenly stop working?

Quickly and repeatedly inserting and removing a USB device can make a USB port unresponsive. When a USB port is in this state, it doesn’t recognize the connected USB device due to which the USB device does not work. Other causes of this issue are the Selective Suspend feature of Windows, corrupted or outdated USB and chipset drivers, corrupted system files, damaged hardware, etc. Refer to the solutions explained in this article to know how to fix this problem.

I hope the solutions provided in this post helped you fix the issue.

Fix Sleep Timer Not Working In Windows 11/10

Most people think that shutting your laptop down and putting it to sleep are the same processes, and to some extent, they are but when a computer is in sleep mode, all its running processes are stored in the RAM while when it is shut down, they are completely abandoned. Another difference is that Sleep on your PC is automated. This helps in the conservation of battery life while not stopping any tasks. You can also adjust the time intervals in which you want your PC to go to sleep, but some users have reported errors with their Sleep timer. They’ve experienced that despite having set a timer, the PC isn’t going to sleep. Today, we will be discussing how, if you’re facing this issue, you can remediate this.

Sleep Timer not working in Windows 11/10

There are 4 ways in which you can implement this fix if the Sleep Timer not working:

Check your Sleep timer settings

Use the Power Troubleshooter

Stop devices from waking up your computer

Use the Command Prompt to check for power requests

1] Check your Sleep timer settings

If you’re experiencing the sleep timer not working as you’d configured it to, the first thing you should do is check on the timer settings in the Control Panel.

From the options bar on the left, select ‘Choose when to turn off the display’

You will see options to set up when to put your computer to sleep, both when it’s charging and on the battery’s standby

Save the settings as you desire and exit the Control Panel

These settings might’ve been messed around with, in which case this will rectify your error.

Read: Different System Sleep States in Windows.

2] Use the Power Troubleshooter

A second solution to this issue is to take the help of a Windows Power Troubleshooter. Microsoft offers troubleshooting facilities for some of its most frequently used utilities to provide quick fixes relating to them. Here’s how you can use the Power troubleshooter.

Press the Windows + ’I’ keyboard shortcut to open Windows Settings

Select Other troubleshooters

Locate where the Power troubleshooter is and tap on the Run button next to it

If there is any system error relating to your Power settings, this will notify you and provide you with an option to fix it.

3] Stop devices from waking up your computer

Devices like your mouse or keyboard, when activated, wake your PC up. So, you can also try disabling this setting from them. We’ll demonstrate how you can disable your mouse from disturbing your PC’s sleep.

Select the mouse you’re currently using and expand to its properties

4] Use the Command Prompt to check for power requests

Another very likely reason for your computer’s sleep breaking is power requests that services may be sending. You can use the command prompt to find out what services are keeping your PC awake and then disable the ones you think aren’t needed. Here’s how:

Search for the command prompt on the taskbar’s search option and select to run it as administrator

Once the prompt window opens up, paste the following line of code there and press enter:

powercfg /requests

The results will be something as shown in the picture below:

As you can see, none of my processes are pulling any power requests at the moment.

Is Sleep Mode bad for PC?

There’s often a concern among people whether sleep mode is better or worse than shutting your PC down. While it is easier to initiate sleep since all you have to do is shut the lid down, shut down helps your PC in performing self-tests, clearing out RAM, and alerting you of software updates.

Does Sleep drain the battery?

Although yes, it does consume battery while it is in sleep mode, it is quite minimal. In the sleep mode, your PC is in a low power state where power is used only to keep the computer’s state in memory. The startup post-sleep is very quick but that snappy power back move takes in a considerable amount of power.

We hope this helps!
