Razer Synapse

Hi,My microphone is working fine but the RGB suddenly stopped working. I’ve tried multiple troubleshooting steps already but to no avail. It just happened yesterday. Troubleshooting Steps done:1.) Unplug and re-plug cable.2.) Uninstall and Re-install Razer Synapse/Chroma.3.) Uninstall and Re-install Seiren V3 Chroma Driver from Device Manager.4.) Turn on my PC with only the Seiren V3 Chroma plugged in.5.) Try all USB ports including a docking station on my PC.6.) Run my device with Razer Synapse/Chroma disabled. I don’t have an extra computer/laptop to try my device. Is anyone experiencing this as well?

The latest Synapse update (I had one yesterday I think) disabled the automatic profile switch for some applications. The profiles do not switch automatically for Google Chrome or VSCode, but they do work for others like Visual Studio or some games.I tried everything that was suggested in some support threads regarding the faulty profiles switch (there are lots of them apparently, meaning Synapse is quite buggy).Razer, please debug the latest release or give me a link to an older version of Synapse 4.

I formatted my PC a few minutes ago and wanted to install Razer Synapse, but when I try to open it, I get an error (RazerSynapseInstaller.err). Inside the folder, it says (Failed to write installer file (Permission denied)).I’m running Windows 11 and have already disabled the firewall and antivirus, but it still isn’t working.I look forward to a reply.

Now can switch ANC on/off or ambient, but cannot adjust ANC level in Synapse 4 version 4.0.86.2601160905 and beta version 4.0.86.2511170410.Synapse 3 and Audio app are correctly. Since 02-Nov-2024, I reported this issue to Razer Support staff.By the way, last month (10-Dec-2025) Razer Support staff replied me that they tried to fixed.What are Razer doing?

You ruined my ability to make lighting profiles. Haptics have been a huge mess. I'm done. Can't take the abuse of the new Razer. You never finished supporting Lian Li still missing 26 Led fan option for Lian Li TL LCD 140mm fans to be used with Razer Chroma Addressable RGB controller. I asked for Tartarus on large format RGB mousepads in 2019. That has been sitting in beta working for over two months. I told you Clio has low volume. Still not able to hear anything in game from this as a rear speaker. Works with Voicemeeter. I can have actual 5.1 and volume. Haptics are very unreliable and inconsistent. Hammerhead v3 hyperspeed offers THX Spatial Audio App yet isn't supported properly. https://youtube.com/watch?v=lobJbP2ArY4&si=P7vfhEfx1JmWhUab

I’m here simply to advocate for Linux support. I have 3 Razer devices, headphones, keyboard and mouse and they struggle to work with Linux. Us Linux users should not have to settle for third part software like OpenRazer. While I respect their work it should not be on them to have to make these tools. We paid money for our devices, we expect support on Linux. 

Linked Games and Auto Profile Switch no longer works after an Synapse Update (Jan 2026), profile switch doesn't affect the apps i'm using. i did a clean install to the software, the linked games now takes forever to scan games and i can't even add programs to it.

Hi everyone,My device: Razer Blade 18 (2024) – Intel i9-14900HX / RTX 4080 / Windows 11 Home I’m having an issue where Razer Synapse doesn’t start automatically with Windows, or if it does, it launches very late after the system boots. Until Synapse finally loads, my keyboard shows random lighting effects instead of my saved Chroma profile. Here’s what I’ve already tried (without success): Enabled “Start Razer Synapse on system startup” in the settings. Checked Task Manager → Startup tab (Synapse is enabled). Made a custom Task Scheduler entry to start Synapse at login (with and without delay). Set Synapse to run as administrator. Verified that Razer Synapse Service and Razer Central Service are set to “Automatic” and running. Reinstalled Synapse completely (including deleting leftover Razer folders from AppData and Program Files). Despite all this, Sy

I’m experiencing an issue with my BlackShark V3 Pro after performing a firmware update through Razer Synapse.After the update:The USB dongle no longer lights up The dongle is not detected by my PC There is no audio when using wireless modeHowever:The headset still works normally when connected via USB (wired mode)I have already tried the following:Using different USB ports Restarting my PC Reinstalling Razer Synapse Attempting to re-pair the headsetThe issue started immediately after the firmware update, and it seems the dongle may have failed during the process.What can I do?Thank you.

The audio equalizare in Razer synapse 4 is not doing anything to my sound, cant modify anything, the problem started 3-4 days ago. 

what do you neeed for axxaror right,  what armor d oyou  use for cg, nex is week to magic gear, shadow slaps in toa, toa sucks out of all the raids1-10 how much do you like our raxor chair, what about the mouse and pad mic and headphones.i just wish they would get us more clothes

The problemAfter the recent Razer Synapse 4 update, somewhere around the end of April - the beginning of May, my laptop settings tab became completely blank.Exactly the same blank tab as in the image in the topic at the link:https://insider.razer.com/razer-synapse-4-55/kraken-v3-pro-tab-is-blank-70072?postid=236934#post236934Only in my case, instead of "kraken v3 pro" it was my laptop "blade 16".The solutionI managed to fix the problem this way:Delete the "Razer" folder in the directory - "C:\Users\%username%\AppData\Local\"; Open "System Settings -> Apps -> Installed apps -> Razer Synapse (three dots, click on modify)". Click "Repair" in the app that opens.The same actions can be seen in the following videos:https://youtu

Synapse 4 is garbage it doesn't work half the time and the other half it keeps crashing, i have never used such a buggy software in my life, its literally reseting all my profiles to default even if i re-import them or create new ones, if i switch profiles for a differnet game its keeps jumping back and forth from 1 to the other, why this is even available yet is beyond me, cant use Synaps 3 installer "Server access unavailable" im using the Razer Tartarus V2 and its completely un-usable with Synapse 4, why could they not allow us to use Synapse 3 locally i dont understand, those that still have synapse 3 can use it locally 

I’ve seen some others have had some problems with installing Synapse 4, but the fixes either I can’t implement because they’re too technical (using PowerShell) or they don’t work for me (closing any Razer processes in Task Manager).Does anyone have any recommendations for a fix that works and isn’t technical?

Hi, I’ve been trying to recreate Sequence Macro like functionality in Razer Synapse. But for some reason it doesn’t really work well. Any ideas what’s the best way to create a macro like this:  

g, h, j, k, o, p, [, ], c, TAB, LShift, CapsLock, Del, PGup, Numpad4, Numpad5. All have the blue LED disabled. The first day i noticed i was able to get it to temporarily fix itself by unplugging the keyboard , restarting synapse 4, and plugging it back in. but since then this issue persists, i know these LEDs are not burned out. they are just software disabled. I've tried firmware updating and factory resetting the Hunstman Elite. But i wish not to uninstall synapse if i can avoid it. When synapse is off and the keyboard is on default spectrum cycling the blue LEDs remain disabled.I am firmly certain this is a synapse issue but because my keyboard is out of warranty i was forced onto this forum instead of talking to a customer service person. Edit* Windows Dynamic Lighting is off, Razer is set to Chroma RGB.

Synapse 4 – Tartarus Pro 8-Way Input Issue (Still Unresolved)I’ve been dealing with an issue in Synapse 4 affecting the Tartarus Pro for nearly a year now.Functionality that worked reliably in Synapse 3 — especially 8-way directional input (diagonal movement) and simultaneous key combinations — is no longer usable in Synapse 4.Since Synapse 3 has been discontinued, there is currently no fallback option.The issue has been documented through multiple support cases (logs, video evidence, cross-system testing) and has also been reported by other users in the community.Most recently, Razer Support stated that it cannot currently be confirmed whether this behavior is a known issue or an intentional change — nor if or when the original functionality might be restored.After nearly a year, this lack of clarity is difficult to understand.Is anyone else experiencing the same behavior?Any feedback or confirmation would be appreciated.

In Synapse 4, Ultra-Low Latency mode is currently not usable. In the text description for it it says “… as low as ~10ms.When disabled, enjoy gaming grade latency ...” when in fact it should be “… as low as ~10ms. When disabled, enjoy gaming grade latency ...”See screenshot attached.  The forgotten space here makes my BlackShark V3 headset unusable because the absence of the space prevents me from enjoying gaming grade latency. In fact, I haven’t been able to enjoy anything at all after identifying this.ProductSynapse 4Software Version4.0.86.2512101100 REPRODUCTION STEPSConnect any Razer headset product that is compatible with Ultra-lo

Blackwidow V4 Pro and Synapse 4 installed.If Synapse is running and I run other certain apps, like a music streaming app, multimedia keys don’t work there and volume control stops working. As soon as I exit the music streaming app, volume control shows up reacting to the roll bar with significant delay. But sometimes it stops working at all. Only if I exit Synapse, it’ll be working.I tried all the steps proposed by support documentation, like rei-installation of the keyboard driver, Windows update and clean re-installation of Synapse, but they didn’t work.
