Issue

You may experience a situation where:

  • The challenge or Studio (DAW) produces no sound
  • But videos (like lesson demos) still play audio normally

Cause

This is typically caused by your device being in silent/ring-off mode.
Some mobile browsers treat interactive audio (like synths and DAWs) differently from video audio when silent mode is enabled.


Solution

1) Turn Off Silent Mode

On iPhone:

  • On newer iPhones, press and hold the Action Button to toggle silent mode off
  • On older iPhones, use the Ring/Silent switch on the side
  • Make sure silent mode is OFF

On Android:

  • Make sure your phone is not set to Silent or Do Not Disturb
  • Set sound profile to Sound (not Vibrate/Silent)

2) Refresh the Page

After turning off silent mode:

  • Refresh the page in your browser
  • Or close and reopen the app/page

Still Not Working?

If you're still not hearing sound:

  • Make sure your volume is turned up
  • Try closing other apps that may be using audio
  • Reload the lesson or Studio again

Note

This is a known issue with how some mobile devices handle interactive audio. A fix is planned for a future update.
