Problem

When attempting to open a .wav file on the BlackBerry 8830 smartphone, the file does not open or you receive the following error:
An unknown error was encountered

Cause

Summary of Causes

This issue can be caused by one of the following:

1. The .wav file is encoded using GSM® encoding.
2. The BlackBerry Enterprise Server is running BlackBerry Enterprise Server software version 4.1 Service Pack 2 or earlier or the BlackBerry Internet Service is BlackBerry Internet Service 2.2 or earlier.
3. The BlackBerry Enterprise Server does not have Microsoft® Windows® Media Player 9 or later installed.

Resolution

Cause 1

The .wav file is encoded using GSM encoding.

Resolution

The BlackBerry smartphone does not natively support GSM encoding and requires the BlackBerry Attachment Service from either the BlackBerry Enterprise Server or BlackBerry Internet Service. This means that if a .wav file encoded with GSM is copied to the media card it will not play. For more information on supported media types, see KB05482.

Cause 2


The BlackBerry Enterprise Server is running BlackBerry Enterprise Server software version 4.1 Service Pack 2 or earlier or the BlackBerry Internet Service is BlackBerry Internet Service 2.2 or earlier.

Resolution

Upgrade to BlackBerry Enterprise Server software version 4.1 Service Pack 3 or or BlackBerry Internet Service 2.3 to re-encode the .wav file to a supported format for the BlackBerry 8830 smartphone.

Cause 3

The BlackBerry Enterprise Server does not have Microsoft Windows Media Player 9 or later installed.

Resolution

Install Microsoft Windows Media Player 9 or later on the BlackBerry Enterprise Server to re-encode the .wav file.
