Try the following actions to resolve the issue. If the issue persists, proceed to the next troubleshooting step.
Try to duplicate the issue
Validate that you understand the symptoms your are experiencing on the BlackBerry® smartphone. For example, play a ring tone. While the ring tone is playing, change volume and audio settings to make sure the audio is functioning. Use the audio keys on the side of the smartphone to raise and lower the volume. Attempt a test call to check that the volume settings are functional.
Check audio settings
Check the volume settings for ring tones and notifications and adjust as necessary.
You can also increase the default volume for calls. The higher the volume percentage, the louder the volume. To change the default volume for calls, complete the following steps:

For BlackBerry Device Software 6.0
