BlackShark V3 THX/Game Profile bug after firmware update

BlackShark V3 firmware version: 1.3.0.0
Synapse version: 4.0. [removed by moderator]

After the latest firmware update, the Game Profile section in Synapse is not working correctly.

When I select either THX Immersive Mode or THX Competitive Mode as the game profile and then launch the game, THX breaks. The selected THX mode does not seem to activate properly in-game.

After closing the game, THX remains broken. Synapse also gets stuck when I try to switch back from THX to Stereo. At that point, the headset still appears in Synapse, but THX no longer works correctly.

This seems specifically related to automatic game profile switching. THX can work after a clean reset/reinstall, but launching a game with a THX game profile causes it to break again.

    Hello, I have the same problem after the latest update. My Blackshark V3 also doesn't switch to THX mode when I launch the game and doesn't respond to any changes in the application. I also noticed that if I completely close the Synapse application through the task manager or tray. Then launch the game and connect the headphones, and after that launch the application, then everything works until you switch back to the game.But as soon as you return to the game, the profiles don’t work and the headphones stop responding to Synapse. 

    Have You found a solution to this problem?

    Yeah, that describes my issue almost perfectly. I’ve already tried reinstalling Synapse, using the Razer Driver Removal Tool, reinstalling all drivers, and even factory resetting my PC, but the issue still persists.

    Please let me know if you find a solution. I’ll update here too if I manage to fix it.

      Hi everyone!

      My Synapse app just updated, and game profiles with THX settings are working correctly again!

      And when launching games, I can now adjust headphone settings from the Synapse app!

            After 1.4.0_r1 update for BlackShark V3 - almost the same problem, THX doesn’t work at all, changing the switch from Stereo to THX has no result.

            BlackShark V3 firmware version: 1.3.0.0
            Synapse version: 4.0.

            After the latest firmware update, the Game Profile section in Synapse is not working correctly.

            When I select either THX Immersive Mode or THX Competitive Mode as the game profile and then launch the game, THX breaks. The selected THX mode does not seem to activate properly in-game.

            I had a similar issue with THX game profiles after an update. In my case, updating Synapse fixed the problem and the profiles started working normally again. It may be worth checking if there is a newer Synapse update available before trying a full reinstall.

            After 1.4.0_r1 update for BlackShark V3 - almost the same problem, THX doesn’t work at all, changing the switch from Stereo to THX has no result.

            I managed to fix this situation. So what I did was:
            1. Uninstalled Synapse 4 with classic “Apps and Features” menu
            2. Disconnected all Razer devices (2 Fireflies, Seiren Mini, Mamba, BlackWidow Chroma, BlackShark V2 and V3 with dongle, so - everything)
            3. Deleted all Razer related devices/drivers in Device Manager without driver programms right after clicking show hidden devices in “View” menu (except old Razer Surround Audio Controller because I needed it), also in “Software Components” menu, not only everything listed in “Sound, video and game controllers”
            4. Cleaned everything with Razer’s DriverCleanup_22_04_2026 program
            5. Rebooted PC
            6. Downloaded and installed newest version of Synapse 4 (also with Chroma components)

            7. Logged into Synapse, waited for everything to completly load
            8. Connected all Razer devices sequentially, BlackShark V3 dongle - last of all devices.
            9. Waited for everything to completly install
            10. Rebooted PC again

            Everything seems to be in working order as for right now.
