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!

Could we have some feedback on this matter please? Do you have a timescale and/or plan of action to deal with this issue? Are you liaising with the manufacturers? Will you address this with a patch?

Thank you

If you cannot connect, it is likely a different issue. You should start a new thread.

If it was all working fine before the 1803 update (or fresh install using the same 3rd party drivers) it should still work though. A lot of people visiting these forums may not understand the difference between a Bluetooth Audio device failing to connect and failing to work.

In my case the Soundbuds Tag earphone/headset are designed to operate at two different 'quality levels' which are either 'handsfree' (eg for Skype etc) or 'stereo' for listening to music or streamed tv etc. The first works fine but stereo is as if the headset isn't even connected eg tapping the mixer slider doesn't even result in any sound at all anymore (although it worked only very unreliably when 1803 was first tested. Since then I've removed the BT Headset and reinstalled several times and now the stereo part is dead. Microsoft needs to give us an update on the progress so far towards fixing this. I hope this is TOTALLY fixed before they even think of releasing build 1803 for my Lumia 950 phone!

Edit: As an update, I found that doing yet another fresh install of Windows 10 ver 1803 on my tablet in conjunction with using a brand new Bluetooth UART driver (also released in April by Realtek to suit my specific hardware) seems to have fixed these sound issues. Now both stereo and handsfree play fine although the handsfree volume still cant be turned up loud enough when compared to stereo. There are also many functions that still wont work in Windows 10's system -> sound control panel (such as 'test your microphone') but these problems are common with even non-Bluetooth audio. Please Microsoft, ensure the latest and greatest Bluetooth drivers get sent through Windows update as I had to find and install these Realtek Bluetooth drivers manually. The version number I'm using is 1.0.250.2 and the matching hardware in the tablet is a Realtek RLT8723BS combo WiFi/Bluetooth chip.

Hi. I have got Philips htl3110 bluetooth speakers that can`t connect to my laptop since the update. Thanks.

If you cannot connect, it is likely a different issue. You should start a new thread.
