I can't hear any sound/audio

If you are using an iPhone, please ensure first that you haven't accidentally put in on mute. Sometimes this is the case, although it is not obvious.

If this is not the case, please try the following:

  • Please restart the app / the browser

  • If the issues occurred while running a particular module, restart the module.

  • When using somnio in the browser: Make sure you are using Google Chrome, Firefox, Safari or Edge as your browser.

  • Please make sure you are using the latest version of the operating system and the app or browser.

  • Check whether headphones or other audio output devices are still connected (either via audiojack cable or via Bluetooth).

    When using somnio on a mobile device:

  • Check that your device has enough storage space available - at least 500MB, but preferably 1GB.

  • Make sure that your device is not set to "mute" and/or that sound output is enabled for apps anyway.

  • Check if you have no sound on other apps as well. If this is the case, you should adjust the system settings on your device accordingly.

  • While playing a module, change the volume by pressing the volume buttons.

  • Uninstall the app first, and then download it again from the App Store/Play Store. Your previous progress will not be lost.

  • If these steps do not make a difference: Please try to launch the app or module where the error occurs using a different device (e.g. your laptop instead of your cell phone or vice versa).
