Windows 10: Bluetooth Speaker connected but not listed as Sound Output Device

Hi,So as the title suggests I have a Gravastar Mars Pro speaker which I want to use with my Windows 11 Pc. The speakers had originally worked for me on Windows 10, However, since updating to Windows 11, whenever I go to use them they do not appear as a sound output device, even when they are connected to Bluetooth. I have tried:- Using the Gravastar speaker on my iPhone and Macbook Pro, which works just fine- Other Bluetooth speakers Oontz Angle 3 DS98 and they connect and play sound just fine.- Updating my Bluetooth & Audio drivers.- Using the "playing audio" Troubleshooter and selectin

Can't select paired bluetooth speaker as sound output (Windows 10)

I just got a new bluetooth speaker, an Urbanears Stammen (concrete grey)

I can connect to it from my phone, using Bluetooth, and play back sound no problem. But I can't get my Windows 10 laptop (Dell XPS 15) to use it as a playback device.

I can connect and pair to it no problem, as you see in the screenshot below





It also shows up under bluetooth in the device manager. It's not listed under "Audio inputs and outputs", which I thought it should be, but I can see it under "Sound, video and game controllers".





But I can't select it as a playback device





I found this relevant superuser question: Windows 10 computer paired w/ bluetooth speaker, but doesn't send music to speaker

And I tried the suggested steps listed there, but nothing helped

Any further ideas I could try?

 

Bluetooth Device Connected But Doesn't Appear As Audio Output

I have a Insignia NS-SB216 soundbar. This morning it was connected and working fine. Then for whatever reason my PC crashed and I had to restart. Now the soundbar is connected but it doesn't appear as a sound output device so I have no sound. How can it
be connected but not be selectable as an output? Instead I have "streaming microphones" and the monitor listed (the latter doesn't even have speakers). I have turned Bluetooth off and on and removed the device completely and reconnected. It's still connected
but no matter what I do it will not be listed as an output device. Now I have no sound due to a random crash.

 

Bluetooth Speaker No sound Issues

Since you seem to be able to connect to the speaker via bluetooth, the next thing I would check is what Audio Playback device is set as the default. To check this, navigate to Control Panel > Hardware and Sound > Sound and you will see a box that looks like this:




You should see the connected bluetooth speaker listed on the playback device list. Right click on the device and select "Set as default device". You can also right click the device and select "test" to send a test chime to the speaker. If you right click the device and select "Properties", there may be a tab for "Levels" which allows you to set the volume output from the computer (not sure whether bluetooth devices have this option). Lastly, ensure the volume on the speaker itself is loud enough to hear.
