Razer Synapse 4

Synapse 4 fails to detect the default audio device in Windows. Despite the correct headset, the BlackShark V2 Pro 2023, being selected in both Windows settings and the Control Panel, Synapse 4 repeatedly prompts to set the headset as the default device. As a result, none of the headset feature's function, the microphone, volume controls, or EQ settings work. Multiple attempts at reinstalling, restarting, and troubleshooting have not resolved the issue.Thanks. 

I downloaded razer synapse to uninstall a macro on my hunstman mini and everytime i open the application of synaspe it loads up shows me the log in screen then after a second it closes not giving me a chance to log in, without deleting the macro i cant use my keyboad because the macro is spamming keys which was placed by accident but now cant delete it. Any advice/help would be greatly appreciated.

For the last few days now every time I boot up my computer Razer Synapse 4 says that my local profiles don’t match the ones that are stored in the cloud. I note that the local settings are newer and I remember that I did recently make a small change so I choose to keep my local settings, but for some reason it doesn’t want to sync those settings to the cloud. I know that there’s a little spinning circle-type-thing that shows up in the corner whenever it syncs to the cloud but that shit never shows up anymore. I’ve tried to make small changes on all my devices in the hopes of that triggering a sync but nothing seems to want to work, so I’m asking here if any of you know of a way to sync profiles manually. I’ve looked through all the menus I could find in Synapse 4 but haven’t found anything but it’s possible that I could’ve just missed it. Based on the things I’ve read in the last few hours I suspect that there sadly isn’t a way to do this so I’m prepared for disappointment but I want t

Hello,I’m having an issue with my Razer Huntsman V3 Pro Mini.I created a profile where I set up some keys, as shown in the attached image, and then I saved it to the onboard memory. However, once I close Razer Synapse and reopen it, even directly, the activation mode turns on for all my keys automatically without me doing anything. I want to clarify that I haven’t pressed the Fn/Tab combination either. Sometimes, it happens the other way around: the activation mode turns off completely. The Rapid Trigger, however, remains unchanged. I even tried saving my profile to each slot in the onboard memory, but nothing works.Thank you in advance for your help!

I just downloaded Razer Synapse 4 and I’m trying to get it to recognize my Naga V2 Pro gaming mouse. I checked with Razer to see if the mouse is supported by Synapse 4 and it is. What do i need to do to make this happen inside S4? Howl do l program or configure the buttons? I’m sure that I’m missing something easy. Some directions that are simple to follow would be greatly appreciated!. I’ve been on this for two days now.Thanks!I created another. question earlier. I think this one is more clear.

I’m trying to program the buttons on my new Naga Pro. I’ve downloaded Synapse 4 from Razer and I’ve opened it and selected my device, but I am not seeing anyway to do this. I’m sure it’s something easy that I’ve missed. Could anyone please give me directions on how to do this? A simple explanation would be much appreciated!Thanks! 

Before synapse 4 everything was fine, custom key mapping, chroma and linked games but now, my key mapping doesnt work, chroma rgb’s reactive and ripple both dont work with any key except for fn and linked games keep doubling my games. I am using Razer Ornata v3

I finally made the switch to Synapse 4 and found the contents of the Synapse and Chroma app windows would flicker and glitch like crazy. Luckily I’ve seen this once before and know it happens when an app doesn’t play nice with G-Sync variable refresh rate. The workaround is to create a program profile in the GeForce drivers to enforce Vertical sync for the RazerAppEngine.  

I recently bought the kraken kitty v3 pro and it will not connect to Razer synapse wirelessly. I can connect it fine to my pc via Bluetooth however the mic quality is poor and I am unable to hear any video game I play on it despite messing with the audio multiple times. I am able to connect to the Razer synapse with a wire connection but would appreciate it if I can connect wirelessly since that is the main reason I bought these head phones Any help is appreciated 

I downloaded Synapse 4 today and ran into a problem when putting my PC to sleep. I have a NAGA V2 PRO and usually charge it with a USB cable while my PC sleeps. On Synapse 3 this worked fine but with Synapse 4 it wakes my PC less than a second after I put it to sleep. It only happens if the mouse is plugged in and charging and I know the issue is Synapse because if I close the program before I put the PC to sleep it works normally which isn't too much trouble but is tedious to stop the program when I get off and start it back up the next session. Ive also tried turning off the mouse’s ability to wake the PC in device manager but it only works if I do the same for the keyboard as well which leaves me with only the power button on the PC case to wake it up.

This functionality was promised to be ready with Synapse 4’s public release, so why it is still not available?

Hello my friends, I’m trying to add a key on my Blackwidow V4 X that will let me cycle trough my tartarus v2 + naga trinity profiles in sync.I expected to be able to pull this function straight in the Macro designer, but for some reasons you don’t get Profile Switch options on there.Is there any way to work around this lack of functionality?Is it planned to be added to Synapse 4 anytime soon? Thanks kindly.

Hello i have Synapse 4 installed. I have 3 Profiles Basic LOL and POE2 they are backup in the cloud and everything. All was good until the other day when my POE2 profile didnt work properly. Its show in the selection menu but when i go to make changes to it. doesnt change anything also the game that is link to it cannot be unselected. So i did what everyone would do i deleted the profile. That obviously didnt fix anything. No the profile is gone i can make a new one but the game that was linked to it still shows as selected so the new profile i made can be use with this game because still show that is link to the old one. I have reinstalled the software try clearing the drivers, No success so far.  Thank you . Have a great day 

Just bought a Blackshark V3 headset and wanted to test out the THX Game Profiles for Battlefield 6. They posted on Razer official facebook page that it was added in October 2nd. I can’t activate it. I checked several posts on reddit and V3 owners have the same issue while the older headphones are working fine with the THX profile. This is false advertising and I want to ask ,what are you waiting for RAZER TO ADD IT FOR YOUR NEW HEADSETS!!! THEY WON’T FIX UNTIL ENOUGH PEOPLE COMPLAIN ON SOCIAL MEDIA. What incompetence!! 

aether monıtor lıght bar Let's connect this to synapse 4. Can anyone help? 

Hi, I have a custom scroll profile for my Naga V2 Pro mouse. I also have browser detection on. I noticed the scroll profile does not go back to my custom profile when I come from a browser window but the default values for the custom profile are used. Does anyone else experience this?This is with Synapse 4

I’ve used the Razer skill to set up lighting routines for a couple years.  It suddenly stop working in Synapse3.  Went through the steps of reconnecting the amazon and razer accounts, and it completes as usual but the skill never enables in Alexa.  Installed Synapse4 with same results.

I have a Deathstalker Pro. Using it with default keybinds is fine. For programs that make the distinction between Enter and Num-Enter, it works as intended.However, if I want to re-program a key or mouse button to ‘Enter’ in Synapse 4, the software will always recognise it as ‘Num-Enter’. Input: EnterOutput: Num-EnterThis isn’t my area of expertise, but I believe Enter and Num-Enter share a code, and therefore the distinction has to be made by a secondary parameter. Or maybe you need to sacrifice a lamb to an old Macintosh? I don’t programming.  Considering how commonplace the distinction is in software, this severely limits the usability of programmable keys..QUESTION: Does anyone have a workaround? Is this something that could be solved reasonably easily?

Hey all, Synapse 4 was working perfectly fine until I decided to give it a refresh by closing it from the system tray. I relaunched it, it automatically updated, and now my laptop (Razer Blade 16 2025) is not being detected. It’s listed as ‘disconnected’ under connected devices.I have uninstalled it, repaired it, performed a windows update, and rebooted my laptop multiple times to no avail.  It seems like a random update to synapse caused this issue, since it was working perfectly fine until I restarted synapse. I use synapse for smart battery charging, etc, so I am kind of reliant on it working properly.  Coming here to see if anyone else is experiencing this issue. 

I created a new profile, but when I try to log in, I get the text error "Emily 401." The app just takes forever to load.Can you tell me what the problem is?

Using the most up to date version of Synapse 4 and have Huntsman V3 TKL and Blackwidow V4 75%. Here’s the issue I’m encountering:When I first plug in each of the keyboards, Synapse 4 shows the usual thing of the firmware getting installed and a Windows notification to restart which is perfectly fine and normal.  However after that whenever I disconnect one keyboard and plug in the other, I get a Windows notification again that a restart is needed, which should not be happening.  On top of that if I don’t restart the computer, whenever I use the volume wheel, instead of the volume going up or down it scrolls the webpage up and down instead. 

Hello all, After recently upgrading to Razer Synapse 4, I noticed that the audio quality of my Razer Kraken Ultimate headset has been completely ruined. The audio levels get to an abnormally high level to the point where the audio crackles and cuts out to a really quiet level before quickly raising its own volume and repeating the process. Raising or lowering Windows volume has no effect, the volume stays constant. After some digging, I discovered that the “Device Default Effects” setting in Windows Audio Settings were the culprit. However, by turning the effects off, it completely disables all the features that Synapse offers (I personally use a custom EQ for my headset, turning this off disables the EQ).  I tried going back to Synapse 3 to see if it fixed the issue. The issue was temporarily fixed until I opened a game. My volume became abnormally loud and everything started crackling and cutting out.  Does anyone know what is truly happening or have a fix for this? Or is this a prob

I have purchased the Razer Freyja haptic gaming cushion and am trying to use for Sim racing. I have Simhub but cant see the Freyja when I try and add a new device. I have it connected, on and have the Razer Synapse app aswell. No idea how to connect it.

Hello, could you please tell me if support for the THX Competitive mode is planned for the game Arena Breakout: Infinite?
