Question Bluetooth speaker not playing

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

List of all connected peripherals.

Wired or wireless network?

What audio card are you using? Source?

Have you tried reinstalling the drivers?
 
So I'm assuming you're trying to connect your laptop to your speaker. When you switch the speaker on does it still show up 'Bluetooth and other devices' and does it show connected?
Does it show up in Device Manager and if you click on Properties is it working. Are drivers up to date?
Is it set as Default in Sound panel in Control panel?
Have you got another device, phone you can connect and see if speaker works.
