If you are testing your headphone or your speaker but all of a sudden encountered an error that says, “Failed to play test tone” in your Windows 10 computer, worry not for this post will walk you through how you can fix this problem. The test tone is used to check the right-left balance of the headphones and speakers in your computer, however, if you are not able to use it, there are several options you can check out.

Aside from these, you could also disable Audio Enhancements or you could also change the default test tone rate and bit depth.

Option 1 – Try to run the Playing Audio Troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to restart the Windows Audio-related services

The next thing you can do to fix the problem is to restart the services related to Windows Audio. Although the audio services start automatically on every system boot, there are times when they might fail to start. Thus, you can start these services manually by following these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Services Manager.
• Then look for the services named “Windows Audio” and “Windows Audio Endpoint Builder”.

You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 4 – Try changing the default test tone rate and bit depth

Windows selects a default test tone rate and bit depth depending on your headphone or speaker. This allows you to look for the best sound quality from your audio output device. So if your headphone or speaker has some problems with the default settings, then it’s no wonder why you’re getting the “Failed to play test tone” error. To fix this, you can try to change the default test tone rate and bit depth by following the steps below.

• First, you need to open the Windows Settings panel and then go to System > Sound.
• Next, look for the Device properties option located on your right-hand side and click on it.

What is Error 0xe0434f4d?

Error 0xe0434f4d displays when a remote computer runs an instance of the SQL Server 2005 but it fails to initialize. When the plan is started, this error displays in a status window on the SQL Server. Also, when the Update-OffilineAddressBook cmdlet is started in Microsoft Exchange Server, this error can occur.

Solution

Error Causes

Error 0xe0434f4d can occur for possibly two main reasons. The first one is when the System Attendant Service is not properly running, and the second when you don’t have the permission to run the update. Other causes are when the .NET Framework 2.0 security does not allow sqlplanlaunch access to run from a shared network. Another cause is when the Offline Address Book (OAB) is not found in the Configuration Domain Controller server that the server of OAB generation uses.

Further Information and Manual Repair

In case you didn’t know, the Offline Address Book generation server is a mailbox server, and in order to resolve error 0xe0434f4d, you will have to replicate the OAB object to the Configuration Domain Controller server. In order to do so, follow steps:

• Go to start and click on All Programs, then go and click on Microsoft Exchange Server 2010. Click on Exchange Management Console
• In Exchange Management Console, go to Server Configuration and click on Mailbox
• In the details, go to mailbox server that generates Offline Address Book and right-click it, then go to Properties
• In the Properties, click on System Setting and locate the domain controller name in the box that reads Domain controller servers being used by Exchange

Make sure the OAB object is reproduced in the Configuration Domain Controller Server. Follow these steps to do that:

• Go to Start and click on Run. Type Adsiedit.msc in Open box and press Enter. Right-click on ADSI Edit and click on Connect to
• Locate a list reading Select a well-known naming context, and from there select Default naming context. In a Select or type a domain or server window, type FQDN (fully qualified domain name) of the Configuration Domain Controller server which was determined in step 1, and click OK
• Expand Configuration [dc.domain.com], expand CN=Configuration, DC=domain, DC=com, expand CN=Services, expand CN=First Organization, and expand CN=Address Lists Container
• Click on CN=Offline Address Lists and make sure the OAB object is listed on the details pane

When the OAB generation server receives this, then it will connect to the Configuration Domain Controller server and will locate the OAB object. If the OAB generation server is unable to find the OAB object, then the error will return on the cmdlet. On SQL Server, you should change the .NET permissions to allow sqlplanlaunch application access to run from shared administration. For that, follow these steps:

• On ArchiveIQ Server, open System from the Control Panel and note down the computer name
• On SQL Server, log in as administrator and open the command prompt
• On the command prompt type, ‘C:windowsmicrosoft.netframeworkv2.0.50727caspol.ece –m –ag l – url file:\[Archive IQServer Computer Name]AlQRemote$*FullTrust and Press Enter. Type yes and press Enter again to confirm the permission changes.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Error Code 0x80073afc - What is it?

Error code 0x80073afc deals with an antivirus program first built into Windows 8/8.1 This error occurs when Windows Defender, the built-in anti-virus software in Windows 8/8.1 and higher, does not start automatically and users attempt to manually start the program. During the initialization period of the program start-up, something goes wrong and users get a 0x80073afc Error message. The error message states there was a problem with the initialization of the program. Windows Defender provides protection of your computer and it is advised by the Microsoft Corporation that you ensure it starts up automatically on every start-up.

Solution

Further Information and Manual Repair

Users have found several manual repairs that have fixed the problem without needing to contact technicians for extra help. While the methods below should solve your problem easily, if this is the first time you have encountered the issue you may want to do a simple restart. This has fixed the problem for some users and is the easiest first troubleshooting move. If it doesn’t work move on to the methods listed below, which are easily completed without extra help.

Before trying any of these methods, please make sure that you are logged into a profile that is listed as the administrator of the computer of his administrative powers enabled. If this is not the case you will not be able to complete the following methods. Please log out and log back in on the administrator profile.

Method 1:

First, check to see if you have a third-party anti-virus program installed on your computer. Some users believe that the built-in Windows Defender program is not powerful enough to handle the safety of their computer so they usually download a third-party program. However, that program may have caused a conflict with Windows Defender and may not allow it to open. If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.

Method 2:

If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.

First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.

Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.

The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.

However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method. 

Method 3:

If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.

For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.

If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.
