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

Anonymous

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!

Can someone answer me a simple question: is there a solution for this problem yet?

I have a Monic Psyc Bluetooth speaker which worked fine before the update and now I have to use a third party ap to control the volume.

That's great for you, but not for the people like me for whom it's not working on 1803 and it was before the "Upgrade". There is no fix for the Broadcom drivers. If you go to the Broadcom site this is their response:

Windows drivers for Broadcom Bluetooth devices are no longer posted here. They should be available through Microsoft's Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update, or contact the device manufacturer.

If I go to the device MFG (ASUS) they tell me to go to either Microsoft, or Broadcom, as it's a Broadcom chipset.

Like I said it's a MS problem as it was working before 1803 and not now.

Although I accept this is a problem that started for you (AND I) with the upgrade to Windows 10 over 1803, the fact that your BT UART hardware makers haven't easily made their 1803 compatible drivers available (assuming these are actually developed) does not automatically make this Microsoft's responsibility.

I'm sorry to read that you're getting the runaround with much buck passing in terms of how you can find suitable drivers. I too had to do some searching and in the end I didn't find the drivers on the chipset manufacturers or my tablet manufacturers websites but on a third party 'driver specific' website. It would have eliminated the problem altogether for me if Windows Update (or even the version/build update itself) had made updated drivers available and installed them but we don't know whether the chipset makers had these drivers available in time and had released them for Microsoft to make available this way.

A search on the Microsoft Catalog website for your specific Broadcom BT chipset may be helpful but in my experience newer drivers will not always be available here in easy to install packages.
