Windows 10: Sound wont play through bluetooth headphones despite them being connected

I have connected my JLab bluetooth headphones and they appear listed in sound devices but are labelled as 'dissconected' even when bluetooth settings shows connected and I am unable to set as default device or update the driver as these options are all greyed out.Is there any way to fix/change this or is it a case that its just not possible. I have Windows 10.

Cannot connect to bluetooth headphones after upgrade to Win10


I upgraded my Lenovo W530 running Win7 Pro 64 bit to Windows 10. After the upgrade I can no longer connect to my bluetooth headphones which worked before the upgrade. The bluetooth radio is on. When I click Connect in the Action Center it shows that the headphones are connected but they are not. The headphones (actually my hearing aids) play a notification sound when a bluetooth connection is made and I never hear that sound. If I play music the sound goes to the speaker, not my headphones. I have removed the headphones and repaired them. I have checked that all of the bluetooth device drivers are up to date in Device Manager. I would really appreciate any suggestions to solve this problem. Thanks.

 

Bluetooth headphone connection - says connected but no sound plays

I have had a seemingly unsolvable problem with connecting my bluetooth headphones to my laptop running Windows 10. For reference, I was using identical headphones until they were broken recently and bought the same headphones as a replacement, and was not
having this problem before now.

I had a lot of difficulty getting the headphones connected to my computer, but I was eventually able to do so after going into Bios and disabling and then re-enabling the bluetooth function.

However, now the computer simply says the headphones are connected but sound continues to play from the computer speakers.

I have tried running troubleshooting. Bluetooth troubleshooting just said that my device wasn't plugged in - I don't know what that means in this context. Sound troubleshooting also did not fix the problem.

I have also tried updating the main bluetooth and sound drivers. This did not help.

When I right-click the "headphones" under sound and click connect, nothing happens.

This seems to be a common problem, but none of the suggestions I've seen in other threads have helped me.

I've included a number of screenshots for reference:

 

Windows: Wireless/bluetooth headphones disconnect and then reconnect without sound if pc stops playing sound

Windows version: 10 pro, version 10.0.17134 Build 17134 (according to system information)

headphone brand: 3sixT wireless bluetooth headphones
laptop: surface laptop

Issue:

Headphones connect to laptop, listed in bluetooth settings as connected for voice,music

If I don't start playing any sounds (music, youtube etc) in the next ~30 seconds after connecting, the headphones alert me that they have disconnected and reconnected, but now they list only voice connected. Same thing happens if I was listening to something and stop/pause it for too long.

They are no longer available in the audio output changer in task bar when this happens and any audio played goes through laptop main speakers.

The device manufacturer (3sixT) does not provide any drivers and they seem to use the standard bluetooth headphone drivers available on whatever system they are connected to.

These headphones connect without issues to my phone (android); issue only seems to be with my laptop.

Unable to find many discussions of similar issues, and those that I could used outdated advice / settings that no longer exist (one suggested something in power settings for the device under the device manager page, but that setting/tab doesn't appear for my device)

tried uninstalling/reinstalling drivers, rolling back drivers, making sure bluetooth service start automatically... Nothing seems to work

Any ideas how I can resolve this, so that my headphones can sit quetly for any amount of time without disconnecting / reconnecting without dropping the 'connected music' setting?
