If you ever don’t hear any sound while in the iOS app, this article may help you.

One thing to know is that if your phone/tablet has been asleep or the BlueRail App has been left in the background while you use other apps, the sound may not work. This can be rectified by closing the app completely (double-click and swipe the app upward) and restarting the app.

If this doesn’t solve your problem, here are a couple of suggestions for getting sound working:

First, make sure the BlueRail app is turned off entirely (and not running in the background) .

Check the little mute slider on the side of the phone/ipad.

Use the volume buttons to turn volume up.

Touch the home button and slide finger upward to bring up the grey settings bar (may take a couple of attempts). Make sure the volume is all the way up on this screen. On this same screen, make sure the “moon” (do not disturb) is turned off.

Now see if the sound is working.

If not, the two things to try are:
1) go into sounds and switch ringtones momentarily.
2) restart device.

Also, some iOS devices give you the option of using the little side slider to “lock orientation” (instead of for muting purposes). This option is generally controlled from:

Settings>General>Use Side Switch to: Mute System sounds / (Lock Screen Rotation )

If you have the side switch set to “lock screen rotation” then the system sound control is in the task bar. Access the task bar (described above), swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
