There are a couple of things you can check if your app isn’t playing any sounds. Try the steps below and see if this sorts out the problem:

1. On the app tap Profile.
2. On the Profile page tap Account.
3. Scroll down and tap Notifications.
4. Tap Play Job Offer Alert and if don’t hear a sound, try adjusting your phone’s volume.

If that doesn’t fix the problem try one of these, depending if you’re on iPhone or Android.
