Leviathan V2 Settings Broken After Synapse 4 Update – EQ and THX Spatial Audio Not Working

Hi everyone,

After updating Razer Synapse to version 4, all the settings for my Leviathan V2 soundbar have stopped working.

  • The equalizer doesn’t respond at all.

  • Switching to THX Spatial Audio is disabled inside Synapse.

  • Along with the update, a separate THX Spatial Audio app was installed. This app requires a paid license, and only started a 15-day trial.

  • The sound quality on the soundbar is now terrible compared to before.

I never had to pay separately for THX Spatial Audio in Synapse 3, and everything worked fine.

Can someone please advise:

  • How can I roll back to Synapse 3?

  • Or is there a way to get the EQ and all settings working again in Synapse 4 without paying extra?

Any help or guidance would be much appreciated.

Thanks in advance!

I confirm that if you connect the panel to your phone via Bluetooth, the sound is good. If you can't fix it, please distribute the THX keys.
