Windows 10 version 1803 April 2018 update broke bluetooth volume control.

My pc automatically updated to the April 2018 update, version 1803.

After restarting my PC I notice my volume control via Bluetooth will not adjust the volume anymore. Speakers are Creative T30

However if I am in WMP or iTunes the slider changes the volume.

If I use my Microsoft keyboard volume keys or the speaker Icon on the taskbar the slider moves but no volume is changed. However if I slide all the way left the volume turns off.

Anyone else having issues.

Any ideas or is a Microsoft patch already required?

I have tried uninstalling driver and rebooting but no change.

Cheers

Microsoft is aware of reports that 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.

To resolve this issue, first make sure you’ve installed the latest Windows Updates.  A solution was included in the October 24, 2018—KB4462933 (OS Build 17134.376) update for Windows 10 version 1803.  To check for updates, select the Start button, and then go to Settings> Update & security> Windows Update, and select Check for updates.

Three devices that are known to experience the issue will automatically have the Absolute Volume feature disabled and should no longer experience the issue once you’ve installed KB4462933:  Creative T30 Wireless Speakers, Edifier R2000 DB, and the JBL Go.

For other Bluetooth devices, once you’ve installed KB4462933 or once you've installed Windows 10 version 1809, you can resolve the issue by disabling Absolute Volume manually by making a change in the registry.  (Warning:  Serious problems might occur if you modify the registry incorrectly. For added protection, back up the registry before attempting to modify it.)

To disable the Absolute Volume feature manually:

1.     In the Search box, type cmd.  Right-click Command Prompt in the Search results and select Run as administrator.

2.     In the Command Prompt window, type the following command:

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

To re-enable the Absolute Volume feature:

1.     In the Search box, type cmd.  Right-click Command Prompt in the Search results and select Run as administrator.

2.     In the Command Prompt window, type the following command:

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

You may need to restart Windows for the registry change to take effect.

Windows bluetooth dev here

If anyone can't control their BT speaker/headphones volume from the PC after the update, can you share a product link to what device you're using?

We added "absolute volume" in the last update which lets the Windows volume slider directly control the local volume of BT speakers/headphones who support it.

Sorry to hear this is happening, I already made a note to look into the Creative T30/T50, Edifier 1700BT, JBL Bar 5.1, we want this to work as best as possible so let me know the devices you're having issues with and we'll look into it.

Thanks guys!

    I use Anker BT Audio hardware with my computer - Soundbuds Tag Earphones Headset. The only related listing I have under 'Sound, video and game controllers' is listed as 'Soundbuds Tag Stereo' and it's only listed there once. If you have multiple listings for the same thing there, you could try removing it from your Devices under Bluetooth and other devices, Audio. Tap click on it and select remove device. After rebooting the computer with your Anker speakers switched off, if there is still an entry for them in Device Manager, you should be able to remove that. When you then go to install the speakers again, only the needed entries should appear in due course.

    I'm curious as to what's listed for your computers built in Bluetooth hardware (its tucked away in Device Manager under 'System Devices' under the name of Realtek Bluetooth UART Bus Driver in the case of my computer). It's important that the Bluetooth hardware built into the computer (or BT USB adapter plugged in to give this capability) has the latest and greatest drivers designed for this OS update -if not, the hardware maker should come up with some. The driver date for my computers built in BT hardware is 12/04/2018. Unfortunately, even though these drivers are in Microsoft's driver catalog, they weren't even updated to this revision using Windows Update when I tried - I had to manually go out and search for the updated drivers.

    I posted this on the other thread mentioned in here. I thought I'd through my experiences with the "work around" on here, just in case someone else is experiencing what I'm going through with the work around.

    Be careful with the suggested solution. I had problems with it each time I implemented it. Windows had to repair itself, so I finally gave up. I'm glad it works for some, though.

    I may have to do a back-up and try it again with my Anker Soundcore Mini device. I think part of my problem is that there are two Anker devices listed under "Sound, Video and Games Controller". I've tried updating the driver on each of them. Each time I'm asked to restart and that is when all the problems begin. Just thought I'd throw this out there.

    Are you able to test if this new build also allows the new unified Bluetooth volume control that 1803 brought in?

    Unified volume control is where the BT device volume control and the Windows volume control are in sync and thus there is one virtual volume scale controlled by two devices. For example, my PXC550 Headphones can control the Windows volume and Windows can control the headphones volume in real-time, dynamically. 

    The issue in this thread is about those BT devices that do not support this "unified volume" feature and Microsoft's failed implementation of it causes the Windows volume to have no affect. 

    Yes, I can confirm that is the case. The numeric value on the speaker increases and decreases in conjunction with the keyboard input on my laptop. It is real-time and dynamic as you described.

    FYI: I didn't re-pair the speaker or reinstall any bluetooth suite to achieve this, it just worked as advertised once the build had installed. I don't want to test a fresh pairing in case I lose the functionality.
