A. If you can hear a song in iTunes you should be able to hear the sounds. If you can't first check that your speaker is turned ON. In the iPhone there is small mute switch on the upper left side. It should NOT be set to red, as that means the speaker is muted. Next check your volume is up. On the iPhone and most 2nd generation iPod touches there is a narrow black button under the mute switch, push the top half to increase the volume, push the bottom half to lower it. On the iPod touch older models there is no hardware volume control - press the "home" button twice to bring up the software audio slider.

Next check in Settings->Sounds that your Ring volume is set to maximum so the sounds will be at there loudest. When you move the ring volume control you should hear the ringtone you have selected. If you don't something is wrong with your device.

If none of these solutions work try soft rebooting your device (hold down the home button and the screen button at the top of the device at the same time until a reset slider appears). Reset the phone then press the screen button to restart it. If this does not help the last resort is to reinstall the iBird application. Delete it from the phone and then sync the phone to iTunes and reinstall it.
