### No sound when activating Outputs

If Outputs are not making sounds when activated, check the following:

1. In the [Control Settings](/think2switch-knowledge-guide/setup-guide/control/control-settings.md), check that "Mute Sounds" is disabled.&#x20;
2. Check that your device has the sound volume turned up.
3. If using an iPhone, check that the Ring/Silent switch on the side of your device is not on.
4. Ensure headphones are not connected to the device (Bluetooth or wired).
5. Restart the device.

### Headset Not Discovered

If your Muse headset is not appearing in the list of discovered headsets:

1. Ensure Bluetooth is turned on.
   1. Open the iOS Settings app and go to Bluetooth.  Ensure Bluetooth switch is on.
2. Ensure Think2Switch app is permitted to access Bluetooth. &#x20;
   1. Open the iOS Setting app and go to Apps -> Think2Switch.  Ensure Bluetooth switch is on.
   2. If the Bluetooth setting isn't there, that means the Think2Switch app hasn't tried to access Bluetooth yet.  Follow the instructions in [Connecting your Headset](/think2switch-knowledge-guide/setup-guide/connect/connecting-your-headset.md).
3. Update headset firmware.
   1. To update firmware, download the [Muse](https://apps.apple.com/us/app/muse-brain-health-sleep/id849841170) app from the Apple App Store and follow the update [instructions](https://choosemuse.my.site.com/s/article/Downloading-and-Updating-the-Muse-App?language=en_US).
