Bluetooth volume broken after Windows 10 1803 update

Thanks for the update and apologies for the delay in getting back to your thread, Dildeep. During this time, have you already resolved the issue with Bluetooth? There was an update on Windows last June 05 which may help with your issue. I highly suggest that you make sure that you're on the latest build. Here's an article that can help you update. Let's also try your theory by making sure that Bluetooth profiles are matched. Make sure that you're Bluetooth version is 5.0 or higher and check if your device is one of the supported profiles in Windows 10 in this article. Also try the Bluetooth troubleshooter as it can automatically resolve issues such as yours. Click How can I try to automatically fix common Bluetooth problems? on this article for further instructions on how to use the troubleshooter. You're also welcome to try the other troubleshooting steps provided on the same article if you ever wish to troubleshoot further.

Update me if there are improvements on your issue.

Hey moderators

Me and many others got the same problem. There is a bigger and older community thread the following link - there is no Microsoft agent helping out though. Would be helpful if this issue was adressed officially by Microsoft now, since this is present for over a month without any proper fix:

https://answers.microsoft.com/en-us/windows/forum/windows\_10-hardware/windows-10-version-1803-april-2018-update-broke/5be7a2a0-2caa-47f0-8054-fba5d7b4f282

This problems persists since day 1 of 1803 update and is very likely caused by the newly implemented "sound settings" inside of the settings app (Go to settings > system > sound > on bottom "more sound settings". What you can see here is this:

On the top, there is a master volume slider (this is the broken one). Below you can see the volume slider for each program capable of outputting sound.

Edit: This has nothing to do with faulty drivers or any type of hardware specific problems like the other community thread tried to solve this. This is just a problem coming with 1803 (I tried downgrading to 1709 and there it works perfectly. However since a clean installed 1803 there is no downgrade option available anymore). That being said, troubleshooter fixes do not and will not work either, because everything works. Except that the volume slider does not change volume. The Windows troubleshooter does not detect this problem.

Edit 2:

Tested on Windows 10 1803

Build 17134.81

With every update available (KB100403 included)

problem persists

Hi Devlin

Thank you for your prompt reply. 

I have installed the new update but the problem persists. 

I have using a generic (non-branded) USB dongle BT device on my Desktop so finding the manufacturer would be difficult. However, I have tried updating all the BT related drivers from device manager and Microsoft Support have tried some obscure drivers that broke it as well. 

I have the latest drivers for my Asus laptop BT drivers and the rest.  

My Desktop PC details are as follows:

Edition: Windows 10 Pro

Version: 1803

Installed on: 17/05/2018

OS build: 17134.81

On a side note, the same behaviour occurred last year with my android tablet connect to the Samsung speakers via BT after a major update. My research at the time pointed to something about BT profiles being changed and mismatching with some BT Audio devices. 

I would like to revert to the behaviour prior to the update even if that means removing the 1803 update.

Hi Dildeep,

Thank you for listing the troubleshooting steps you've performed with Microsoft Support. A driver compatibility issue with Windows 10 version 1803 is a possible cause of your concern. That being said, can you tell me the current OS Build of your Windows 10 system? You can find this information by clicking the Start button, type About your PC, press Enter, and then scroll down to Windows specifications. A new build was just released yesterday, KB4100403 (OS Build 17134.81). If you don't have it yet, I recommend updating your device. You can manually download the update from the Microsoft Update Catalog. You can refer to this page for more information about your System type.

If you haven't tried yet, I suggest downloading the latest Bluetooth driver from the computer manufacturer's support website. This ensures that the Bluetooth driver installed is specifically designed for your device and is compatible with the latest version of Windows 10. Andre Da Costa created a forum article with steps on how to manually install drivers in Windows 10.

I'll be waiting for your reply.
