KB13547 - Unknown error when opening .wav files on the BlackBerry 8830 World Edition
KB13547 - Unknown error when opening .wav files on the BlackBerry 8830 World Edition smartphone
Environment
- BlackBerry® 8830 World Edition smartphone
- BlackBerry® Enterprise Server software version 4.1 Service Pack 3 (4.1.3)
- BlackBerry® Internet Service 2.3
Overview
When attempting to open a .wav file on the BlackBerry 8830 World Edition smartphone, the file does not open or the following error message is displayed:
An unknown error was encountered
Cause
This issue may be caused by one of the following: - The .wav file is encoded using Global System for Mobile communications® (GSM®).
- You are running BlackBerry Enterprise Server software version 4.1 Service Pack 2 (4.1.2) or earlier or using BlackBerry Internet Service 2.2 or earlier.
- The BlackBerry Enterprise Server does not have Windows® Media® Player 9 or later installed.
- The Fraunhofer IIS MPEG Layer-3 codec is not installed or configured on the computer running the BlackBerry Enterprise Server Attachment Service.
Resolution
Complete the appropriate resolution for the cause.
Cause 1
The .wav file is encoded using GSM encoding.
Resolution
The BlackBerry smartphone does not 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
To resolve this issue, upgrade to BlackBerry Enterprise Server software version 4.1 Service Pack 3 (4.1.3) or BlackBerry Internet Service 2.3 to re-encode the .wav file to a supported format for the BlackBerry 8830 smartphone. For more information, see the BlackBerry Enterprise Server Upgrade Guide.
Cause 3
The BlackBerry Enterprise Server does not have Windows Media Player 9 or later installed.
Resolution
To resolve this issue , install Windows Media Player 9 or later on the BlackBerry Enterprise Server to re-encode the .wav file. For more information about downloading Windows Media Player, visit the Microsoft Support website.
Cause 4
The Fraunhofer IIS MPEG Layer-3 codec is not installed or configured on the computer running the BlackBerry Enterprise Server Attachment Service. This is used to encode the files for the BlackBerry 8830 smartphone.
ACM mp3 codecs
- l3codecx.acm - "decode only" (wmp 10 or higher) doesn't encode!
- l3codeca.acm - "advanced" (w2k3 base wmp9 not downloadable for w2k3) decodes all bitrates. Only encodes up to 56kbps.
- l3codecp.acm - "professional" (w2k3 sp1 or wmp10 or higher) encodes and decodes all bitrates
- l3codecx.ax - not acm (wmp 6.4)
Resolution
To resovle this issue, verify that the codec is installed and turned on by completing the following steps:
- Open 'Device Manager'.
- Expand 'Audio, Video, and game controllers'.
- Open the properties for 'Audio Codecs'.
- On the Properties tab find the 'Fraunhofer IIS MPEG Layer-3 Codec' and open the properties.
- Verify that Use this audio codec is selected.
- Close Device Manager.
Verify that the codec is installed to both encode and decode by completing the following steps:
- Open the 'Registry Editor'.
- Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32.
- Look for a value named msacm.l3acm.
- Verify that the file it points to is named l3codeca.acm or l3codecp.acm (this depends on the version of Windows Media Player that is installed. See the additional information section to find out which version is appropriate). Note: The l3codecx.acm codec is for decode only.
- Verify that the file exists in the path specified.
If the registry value is incorrect perform the following task:
- Run regsvr32 (Example: regsvr32 c:\windows\system32\l3codeca.acm or regsvr32 c:\windows\system32\l3codecp.acm ).
- Continue on to the next section to register the correct file
If the registry value does not exist perform the following:
- Do a search of the local hard drive for "l3codeca.acm" (usually in C:\Windows\System32)
- Run "regsvr32 " (Example: regsvr32 c:\windows\system32\l3codeca.acm)
- Verify that 1 of the 2 keys below are listed:
Media player 10 or higher
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32] "msacm.l3acm"="C:\WINDOWS\lsystem32\l3codecp.acm"
Media player 9 or lower
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32] "msacm.l3acm"="C:\WINDOWS\lsystem32\l3codeca.acm"
- Restart the BlackBerry Attachment Service.
Additional Information
ACM mp3 codecs details
Please make sure that the proper codec is registered based on the version of Windows Media Player installed on the BlackBerry Enterprise Server.
- l3codecx.acm isused to decode only and is only available with Windows Media Player 10 or higher. This codec does not encode.
- l3codeca.acm is used to both encode and decode but only encodes up to 56kbps and is only available with Windows Media Player 9.
- l3codecp.acm is used to decode only and is available with Windows Media Player 10 or higher. This codec is used to encode and decode at higher bitrates.
Note: If registry keys are not updated after registering .acm file you may have to update the keys manually in the registry. To update the version of Windows Media Player you may require using Windows update.
