^{(Bluetooth Headphones)}如您所知，蓝牙耳机可以无线连接到您的手机。这种能力使您可以在不使用电线或电线的情况下打电话或听音乐。您甚至可以调节左右扬声器的音量。但是，在Windows 11/10上，范围是有限的，即左右部分不能有不同的音量级别。不过，如果您想单独更换Windows 11/10上的双音量控制耳机^{(change dual volume control headphones)}，请按照以下步骤操作。

如果Windows Update^{(Windows Update)}破坏了您的蓝牙^(Bluetooth)音量控制，并且您需要禁用 Absolute Volume^{(disable Absolute Volume)} ，这篇文章也可以为您提供帮助。绝对^(Absolute)音量功能与某些蓝牙^(Bluetooth)设备不兼容，导致无法调节蓝牙^(Bluetooth)设备的音量。如果您遇到此问题，则任务栏中的音量滑块和设备的音量控件都不会对音量产生任何影响。

在 Windows 11/10 上禁用绝对音量^(Absolute)

每当您更改一个扬声器的音量级别时，另一个扬声器的音量也会自动更改。因此，没有简单的方法可以单独更换双音量控制耳机。一个简单的注册表调整可以使这成为可能。

请^(Please)注意，该方法要求您通过修改注册表设置^{(Registry Settings)}来禁用绝对音量。请^(Please)谨慎行事。

Press Win+R键以启动“运行^(Run)”对话框。

在框的空白字段中键入“regedit.exe”，然后按“ Enter ”打开注册表编辑器。

导航到以下路径地址-

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT

在右窗格中查找名为DisableAbsoluteVolume的条目。出于某种原因，如果您没有找到此条目，您可以创建它。为此，请右键单击 CT 键并选择New > DWORD（32 位）值。为该键分配以下名称 - DisableAbsoluteVolume。

接下来，双击它并将其值设置为1。默认值为 0。

重新启动系统。

您还可以通过执行以下命令使用命令提示符启用或禁用绝对音量：^{(Command Prompt)}

要禁用绝对^(Absolute)音量功能，请执行：

reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT /v DisableAbsoluteVolume /t REG_DWORD /d 1 /f

要启用绝对^(Absolute)音量功能以执行：

reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT /v DisableAbsoluteVolume /t REG_DWORD /d 0 /f

重新启动 Windows^{(Restart Windows)}以使注册表更改生效。

现在，当您右键单击系统托盘中的扬声器图标，选择“打开声音设置^{(Open Sound Settings)}”并单击“管理设备设置^{(Manage device settings)}”时，您将可以看到与之前相同的控件。

当您更改一个扬声器的音量级别时，另一个扬声器将保持静止，不会与另一个扬声器一起改变。

我希望这对你有用。^{(I hope this works for you.)}

How to enable or disable Absolute Volume on Windows 11/10

Bluetooth Headphones, as you know, сonnect to уour phone wirelessly. This ability enables you to talk on the phone or listen to musіc without using wirеs or cords. You сan even adjust the volume of a left or right spеaker. However, on Windows 11/10, the scope is limitеd, i.e., the left and right pieces cannot have different volume levels. Still, if you wiѕh to change dual volume control headphones on Windows 11/10 separately, follow the steps given below.

This post can also help you if Windows Update broke your Bluetooth volume control, and you need to disable Absolute Volume. The Absolute Volume feature is incompatible with some Bluetooth devices, resulting in the inability to adjust the Bluetooth device’s volume. If you are experiencing this issue, neither the volume slider in the taskbar, nor the device’s volume controls have any effect on volume.

Disable Absolute Volume on Windows 11/10

Whenever you change the volume level for one speaker, the volume of another speaker also changes automatically. As such, there’s no easy way you can change dual volume control headphones separately. A simple registry tweak can make this possible.

Please note that the method requires you to disable absolute volume by making modifications to the Registry Settings. Please proceed carefully.

Press Win+R key in combination to launch the ‘Run’ dialog box.

Type’regedit.exe’ in the empty field of the box and press ‘Enter’ to open the Registry Editor.

Navigate to the following path address-

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT

In the right pane look for the entry called DisableAbsoluteVolume. For some reason, if you do not find this entry, you can create it. To do so, right-click the CT key and select New > DWORD (32-bit) value. Assign this key the following name – DisableAbsoluteVolume.

Next, double-click on it and set its value to 1. The default is 0.

Restart your system.

You can also enable or disable Absolute Volume using the Command Prompt by executing the following commands:

To disable the Absolute Volume feature execute:

reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT /v DisableAbsoluteVolume /t REG_DWORD /d 1 /f

To enable the Absolute Volume feature to execute:

reg add HKLM\SYSTEM\ControlSet001\Control\Bluetooth\Audio\AVRCP\CT /v DisableAbsoluteVolume /t REG_DWORD /d 0 /f

Restart Windows for the registry change to take effect.

Now, when you right-click the speaker icon in the system tray, select ‘Open Sound Settings’ and click ‘Manage device settings’, the same controls will be visible to you as earlier.

When you change the volume level for one speaker, the other will remain stationary and will not change alongside the other.

I hope this works for you.
