Code: Alert.startBuzzer() does not work

Alert.startBuzzer() and Alert.setBuzzerVolume() are not supported by the BlackBerry 7100 Series device and later devices.

The BlackBerry 7100 Series device and later devices contain a hardware upgrade that changes the way audio is produced.
Resolution

As an alternative to Alert.startBuzzer(), we recommend Alert.startMIDI(). To determine the method to use, the following tests are performed:

if( Alert.isBuzzerSupported() )
{
Alert.startBuzzer(…);
} else if( Alert.isMIDISupported() )
{
Alert.startMIDI(…);
}

Note: If you use a polyphonic tone, use the above test to check the availability of Alert.startADPCM(). You can do so via Alert.isADPCMSupported().
