Razer Synapse 4

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.

someday i installed razer synapse 4. it was perfectly working for over a half year. one day my hedephones razer blackshark v2 didnt connect to the pc(they were working but i couldnt change setting). after some time synapse stoppped opening. i delete all files connected to the razer and set my pc to factory setting(with all my files). i reinstalled synapse and it still doesnt open. i did all things from guide on youtube and it didnt help. my website version of synapse also doesnt see my devices(basilisk v3 and blackshark hyperspeed v2)

With a lot of people moving from Windows to CachyOS and other Linux distributions, I am yet another person asking the question of Razer:When will you provide official support for Razer products and Synapse on Linux? 

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. 

Everytime I press the mute button on my headset, my mic volume drops to 0.I’ve seen that a lot of people have this issue and although I tried everything to fix this problem, there is no solution yet so I’m waiting for Razer to correct it…

Hello. I constantly face an issue where "RazerAppEngine Window" process prevents my PC from shutting down normally. Sometimes an additional error window pops up during this.When will this be fixed? All of this happens on new PC with a clean Windows installation. It has been more than 1 year since first post about this, but bug is still not fixed.Existing threads discussing this issue:https://insider.razer.com/razer-support-45/razerappenginie-exe-is-preventing-shutdown-74690https://inside

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.

Hello,I recently purchased a Razer Wolverine V3 Pro, and I am currently unable to use it properly due to a critical issue with Razer Synapse.The controller is detected, but Synapse is stuck on "Loading" / "Syncing Profiles", and no changes are applied to the device at all. This makes core features like remapping, RGB, and stick calibration completely unusable.Key Issues:No settings are saved or applied to the controller RGB lighting does not change Button remapping does not work Stick calibration and deadzone adjustments do nothing Synapse remains stuck syncing indefinitelyMajor Concern:The required Synapse services are missing entirely from the system:Razer Synapse Service (missing) Razer Central Service (missing)Only the following services exist:Razer Elevation Service Razer Game Manager Service 3

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.

I just cannot fight version 4 anymore, its absolute trash. Went back to 3 and will deal with any issues after Jan. 20th 2026 or just replace all my gear.

Before upgrading to Razer Synapse 4, I could hold the volume up button to increase the volume continuously. Now I have to keep pressing it repeatedly. However, when I close the Razer Synapse app, holding the button works normally again.Is there a way to keep the app open and still be able to hold the volume up button to increase the volume, without having to spam the button?

Dear Razer Support Team,I am experiencing an issue with my Razer BlackShark V3 Pro headset microphone.Details of the problem:  - When Razer Synapse is uninstalled, the microphone works normally.  - Once Synapse is reinstalled, the microphone stops working completely.  - I have already updated both the headset and dongle firmware to the latest versions.  - The device is recognized by Windows, but the microphone input remains at zero.  Could you please advise on further troubleshooting steps or provide a patch to resolve this issue? I am happy to share logs or perform additional diagnostics if needed.Thank you for your assistance. 

Just bought a new Barracuda Pro headset and a Viper V3 HyperSpeed mouse. Whenever I launch installer for Synapse, I get Server Access Unavailable. Went through all of the troubleshooting steps found online with no luck. Tried to updated BIOS, turn VPN on/off, turn Firewall & Windows defender ON / OFF,  add exceptions etc to firewall, change IPV4/IPV6 settings,  launching installer through earlier versions, trying to install other razer apps first (can’t install anything, same error every time), made sure network drivers and windows is updated, tried wired connection, tried mobile hotspot, WIFI, removed all razer devices and their drivers. Probably forgot to mention a few more since I’ve been at it for hours.Literally nothing seems to make a difference and at this point I’m losing hope which is a shame since there’s so much of the headset features locked behind Synapse and I just bought them today. Any help would be greatly appreciated!

Razer Synapse 4 just randomly crashed on my PC a few days ago, and since then, no matter how many times i reinstall it, it crashes on launch every time, and i think it is because it doesn't have the services that it needs to work. It only ever installs the Razer Elevation Service, and I think it cant install them because it can't get the services package from assets.razer.com, or something. It also just doesn't install the C:\Program Files (x86)\Razer\Razer Services\ folder on my PC. Does anyone having a working synapse 4 installation and has this folder so i can install it through cmd or powershell? Maybe through google drive or something. 

So as the title says, these are what I am using. I am setting up a default profile and I realize this mouse only has 1 onboard memory. That being said I have to ask, how do I save a single profile to the onboard memory. I have 3 profiles but I m only using one, but in synapse 4 I see no icon or anything to “save to memory” like I’ve seen in synapse 3.As some back history, I am dual booting Linux and windows. While the keys default to the profile I pick which is default from the factory, all numbers to its corresponding mouse button number. When I use that profile I get 2 results.Windows everything works as it should….1 is button 1, 2 is button 2 and so onLinux I have buttons duplicating numbers, such as button 5 and button 9 on the mouse output as number 3.I realize there is no  support for Linux, I am just trying to set a profile to stay in memory s the default setup, and go to Linux and it should stay as that As a

Since the update V4.0.86.2605190956 of Razer Synapse on Windows, the button 9 of the Razer Naga V2 Pro mouse cannot be modified at all. Here’s what button 8 looks like, what is expected: And here is button 9. Notice that the turbo function simply isn’t present: Since turbo was activated prior to this update, it still works. However, this update changed something in the behavior which make the function behave extremely herratically. To fix it I had to tone down the turbo on the button 8 for scrolling up. However, due to this bug I cannot do the same for button 9. A partial fix comes in the way of closing Razer Synapse completely. Even though bot

I'm experiencing an issue after logging into Razer Synapse. There's an undeletable default app profile that seems permanently saved in the cloud. It syncs back to my local device every time I log in, and it sometimes prevents me from adding new profiles.

Hi everyone,I've been experiencing multiple serious issues with my Razer BlackShark V2 HyperSpeed running Synapse 4 on Windows 11. I've already had the headset replaced once – the problems are identical on the new unit, which confirms this is a software/firmware issue, not a hardware defect. 1. Dongle not recognized on startupWhen I turn on the headset, it is frequently not detected by Synapse or Windows. I have to physically unplug and replug the HyperSpeed dongle to get it recognized. This happens consistently and is reproducible.2. Volume extremely low until a profile is selectedEvery time I power on the headset, audio is barely audible until I manually switch to or re-select a profile in Synapse 4. Only then does the correct volume apply. This happens on every startup.3. Microphone randomly stops workingThe microphone frequently fails to pick up audio. When it does work, the sidetone ("Abhören" / mic monitoring) feature does n

Tired of using Rawaccel every time I turn on my PC I need to open the program. I want to ask you guys when is Razer going to enable me to fix the rotation of my mouse? Or the hardware is limited and the Razer programmers will not make my Deathadder v3 Pro have mouse rotation? I already sent two feedbacks months ago and still no mouse rotation feature. I need to know so I can make up my mind to buy another mouse with mouse rotation built in.

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

My Razer mouse indicates 2 states via LED: 1. Awaked from sleep and no Synapse detected (Spectrum Cycling LED) 2. Synapse detected and just linked teh mouse (Switched profile’s color LED)Issue: My Razer BASILISK V3 X HyperSpeed does totally not remember my customized DPI and every awaking from sleep reverts its DPI to default. (400/800/1600/3200/6400 DPI) Then Synapse 4 applies my customized DPI list to my mouse again but it spends about 5 secs until the DPI reapplied so it makes me goes mad.The mouse works cool but its software’s awful and completely spoiling customer experiences.Do NOT tell me to update or reinstall Razer Synapse.

Hello all,On one of my PC Synapse 4 is not starting up properly.  During the startup phase, it is downloading files but it doesn’t complete.  It downloads files non-stop reaching 50 000 % + and keep rising. I have all the latest update of Windows 11and without any razer devices connected but it is always bug at this place. Anyone encounter this and have a workaround? Thank you!

AUDIO IN SYNAPSE DONT WORKSRAZER BLACKSHARK v2 PRO 20231.GO HERE  (PROPERTIES) ADVANCED  AND HERE TURN EVERYTHING ON AND IT WILL WORKS AGAIN AND IF NOT TRYWIN+RMSCONFIGAND TURN ON THIS PROCESS   

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.
