did you ever get this figured out? mine just started doing this today… and 4 other people within the last week. Pretty bothered that nobody responded to this in the 2 months since it was posted

I have same issue; tried everything (changing usb port, cable, powering on and off multiple times), but the speaker doesn’t work. The power button and the source button are green, RGB lights are cycling, but the speaker is not recognized by the system.

This is happening to me as well. All other forums I’ve read show absolutely no fix. 

This happened to me today, looks like it tried to update and after the update completed it stopped working. Wouldn't show up in my sound devices in the sound mixer page, nor would i get a sound indication when i plugged in the USB (i had my monitor as the sound source at this time)

When I attempted connecting via Bluetooth it would connect, only to not play any sound and eventually the input light would turn red and i was forced to unplug the speaker as at this point all button were not responsive.

I tried doing a firmware update but Razer’s step by step process wasn’t able to work. After the Bluetooth phase I couldn’t switch it back to PC mode via the input button as I would get a solid red light, forcing me to unplug the speaker,  interrupting the process and I couldn't continue with it. 

Anyways I was able to eventually get it working by going into device manager, uninstalling the leviathan v2 from the “ Sound, Video, game controllers “ tab. After doing this it immediately was recognized after unplugging and re-plugging the USB into my laptop. I know the Original thread mentioned theirs wasn’t showing in device manager but this was just my experience. I immediately did the razer update process again and it worked. 

Hope this helps!

This issue just happened to me. Unfortunately none of your advice worked for me, and I agree that it would be great to get an official response for this problem.

I’ve submitted a bug report in the mobile app along with system logs.

Ok, just wrote a detailed post of how I fixed this - it was Razer Synapse. I dared to call the software “cr*ppy” in my response and this reply section just completely bombed out and I got a red box above it (I assume some kind of error message is supposed to be in there) and I had to reload the page to get it out of that error state.

I don’t know what y’all are doing with your software - but wow it doesn’t look good! I’m not impressed with your brand and I don’t think I’ll be buying any more Razer products.

I have the same issue. Any fix available?

I have a bleutooth soundbar v2x razer leviathan. Often the sound just switches off and i need to reconnnect everything by switchting off pc and box and reconnect. 
Happens weekly. Sometime it says connected but still needs to be connected with bluetooth again. I have the cable in pc so i do not understand why bluetooth is needed when cable is connected. I tried firmware update but it keeps saying error. 
Thanks in advance if you know what to do

This issue is more than two years old. How about a firmware fix, Razer?

Hi, myself and my husband have spent the last 2 day's trying to get the leviathan v2 working, obviously we tried all the suggestions and nothing worked until we read on a post about RAZER SYNAPSE 4 (beta) so we installed it, (as it was the only thing we had not tried). IT WORKED STRAIGHT AWAY YAY . I'm not saying it will work for everyone but it is worth trying. Good luck people  

Has anyone from Razor address this issue? this is extremely upsetting Razor has just washed there hands of this issue.

Having same problem. Bought Leviathan V2 two months ago worked normal until 4 days ago and now it wont work on pc (mobile phone bluetooth connection works normally). It is recognized in synapse 3 and in windows settings but when i play something it dosent make a sound like its not even there connected. Then yesterday I downloaded synapse 4 beta and it worked but today its all the same again. Its recognized in synapse 4 beta and windows but makes no sounds/not working like its not connected. Going to try to plug it in wall thats last option but this is annoying...

I ran into this same problem and was finally able to fix it. I saw where urbansandytaupelab304 had fixed the issue by removing the speaker from the device manager but like the OP, it wasn’t showing up in my device manager. Then I remembered the magic button “show hidden devices” under “view”. There was my leviathan. I uninstalled the device and followed the installation instructions and the computer instantly recognized it and started working. 

Hope this helps.

Showing hidden in device manager, removing Leviathan, restart, bar power off unplug then re-plug usb, bar power on, and its back!

I found the solution by a random YouTube video. Razer if you are seeing this, act like a big company and list somewhere how to hard reset your products so that we won’t need to dive deep into YouTube. 

Solution: unplug the device, press volume up, volume down and bluetooth buttons simultaneously for 3 seconds, plug the device back and power up. Voila. 

I hope Razer someday provides official repair support in Turkey, showing they care about the ‘after sale’, like they already should but I don’t have any hope for that to be realistic.

@PatrickStarD I follow your instructions and I worked for me, I was soo close to giving up.

on device manager, click the Razer Leviathan V2 (leave highlighted) up top where you see icons, nest the the red X is an arrow.  If it is green, then click on that.  It should say  Enable device when you over over that arrow.  After you click that arrow, it will now be dark and pointing down. when you hover over it, it should say: disable device.  That is what I had to do to get mine to work.  

Thanks a lot buddy i almost give up on my 2month old razer leviathan

I had uninstalled and reinstalled Synapse, unplugged and replugged the device, trained my ferret in the forbidden dance, chanted the nine runes of power, rebooted my machine, blah blah, but FINALLY the solution by PatrickStarD above fixed it for me. I’d upvote it ten times if I could!

To reiterate their solution: hold down both volume buttons and the power button at once. Then turn the bar back on, and it will have hard reset and have a fresh chance of showing up in Synapse.

Finally I could change the power saving option that was causing me an issue!
