Bluetooth volume broken after Windows 10 1803 update

Hi there Peter,

Thanks for the update. I've seen that the thread has been on-going for a while now and there are still issues happening on different devices. To help further isolate this, can you provide me the following information for further investigation?

• What is the name of your Bluetooth adapter and it's driver version? You can get this information by right-clicking Start, choose Device Manager, look for and right-click the Bluetooth device and select Properties.
• What is the make and model of your device?

I've also seen that you're one update behind the latest update. Please make sure that you're on the latest build. To check for updates now, select the Start button, and then go to Settings > Update & security > Windows Update, and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available.

I'll be waiting for your updates.

Hey

• I use a bluetooth USB stick with Plug'n'Play (since the mainboard itself doesnt provide BT).

It uses Microsoft Bluetooth drivers - Windows automatically downloaded and installed them right after plugin. Doesnt look like the driver has a specific name. It is provided by Microsoft, version 10.0.17134.1, signature by Microsoft Windows.

• I dont know what exactly you mean by "your device", so here are all specs of my build (self made PC)
• Mainboard Biostar x370GTN
• AMD Ryzen 5 1600
• MSI 1060 6GB
• 8GB 2400 RAM
• 2x 250GB Samsung SSD EVO 850
• If you want to know the connected bluetooth speaker, the name is Creative Sound BlasterX Katana
• Windows Update says that I am up to date.
• I manually checked every device's driver for updates - some of which updated, but didn't cure the problem.

It is important to notice this: On 1709 everything still works just fine - for everyone in the thread I linked - including me. As soon as 1803 is installed, the problem occurs. It is unlikely that this is caused by a faulty or old driver, since many people with different hardware report the same issue. It is more likely that 1803 is faulty itself or has a faulty feature implemented (my suspect is the integration of the sound settings into the settings app).

Hi Ian Ser, 

Thank you for responding. 

I can confirm I have the latest Windows update. 

Not sure what I can do to change the Bluetooth version? I have updated all Bluetooth drivers as well as a Microsoft assistant did via remote support. We also update all sound drivers and they even tried from exotic drivers that ended up breaking the sound. 

All sound and Bluetooth troubleshooters have used with no success. 

Peter has done a good job of explaining the issue as well. I was made aware of the larger thread after I posted this one. And I have been following the recommendations there as well. Non work. I have also contacted, Dell support and Samsung support. They both direct me back to Microsoft, since it is strongly believed to be a fault of the 1803 update and hence can be fixed my Microsoft. 

I use two systems: 

Dell Optiplex 7020 with an aftermarket Bluetooth dongle

Bluetooth driver version: 10.0.17134.1

AND

Asus laptop with builtin Bluetooth

(I will have to get the details later)

What's important is both systems displayed the same problems AFTER the 1803 update. 

Also to note: I use multiple Bluetooth devices and the behaviour is as such on both systems;

AFTER 1803 UPDATE

Samsung DA-670 Speakers: Windows volume slider has not effect on volume (expect mute)

Sennheiser PXC550 headphones: builtin volume slider controls windows volume and vice versa, windows volume syncs with headphone volume. Effectively having one volume with two devices to change it by. (This is new behaviour but working)

Lastly; Android had the very same issue with the same speakers some time last year after a major OS update. They managed to fix it, so I am sure Microsoft can do as well ;)

@ Dildeep

Today an update for Windows 10 arrived (KB4284835). It didn't help with the issue.

In addition, I also had the chance to test this with a Microsoft Surface Pro 4. I only ! used it's integrated bluetooth chip.

When 1709 was installed it worked just fine - volume slider was fully functional.

I updated to 1803 and downloaded every update (KB4284835). Volume slider does not work as intended anymore.

Just like Dildeep described, 0 is muted and everything betweend 1-100 is maxxed out without changing.

@ Ian Ser

The problem even applies on Microsoft's own devices right after the 1803 update.

Again: This is not a hardware specific bug. It simply is a faulty update that broke the volume slider for connected bluetooth devices.
