My Razer device has no sound after Synapse 3 update

| Answer ID: 1902
This article explains why your audio device has no sound after the Razer Synapse 3 update, and what to do to resolve the issue.

Effective February 3, 2026, Razer Synapse 3 will no longer receive updates or support cloud services. After this date, cloud syncing of configurations across PCs using the same Razer ID will be disabled.

Note: Your installed devices will continue to be configurable in Razer Synapse 3. However, if you uninstall these devices completely, you will need to upgrade to Razer Synapse 4 to continue customization.

Download Razer Synapse 4 and migrate your existing Razer Synapse 3 profiles using the Profile Migration Tool to retain access to your configurations. See How to migrate your Razer Synapse 3 Profile to Razer Synapse 4 for instructions.

An update on Razer Synapse 3 initiates the detection of THX Spatial - Synapse and automatically sets the audio playback device to "THX Spatial - Synapse". Change the playback device to resolve this issue.

Step-by-step process

  1. Click on the speaker icon on your system tray.
  2. Set the playback device to your active audio device.
