Please note, this support page may still be updated and modified from time to time. Some solutions have only been tested a few times and may not work on all systems. This problem is rare, so it's been difficult to get enough testing and data to confirm the consistency of some procedures to solve it. If you have further information to contribute that will help others solve this problem (including which steps/procedures worked for you), please e-mail the details to me at the address at starwraith.com > contact. This page can then be updated as needed to provide the latest information on solutions.


Error 3002: Could not load sound at line X

Error 3002 'could not load sound' can occur on systems that lack a standard Windows audio codec. It might occur on a system that has been exposed to past system damage caused by a malware or virus infection, resulting in damaged system files. It might also occur if the user removed the codec at some point or the codec became corrupted/damaged. The default Windows filename is msadp32.acm and it is the Microsoft ADPCM codec. Here are some steps to try and solve the problem. Some of these procedures are not recommended if you are unfamiliar with installing codecs/drivers, hardware, and/or managing the registry as there are risks involved.

If you are familiar with installing and managing codecs, then manually installing the MS ADPCM codec (including the needed registry entries) will likely solve the problem. There are also a few more automated options available via the use of one or more free tools designed to detect and repair/restore damaged or missing codecs.


Program Options
One user reported an optional way to fix the damaged/corrupt/missing codec by using some free tools which may help automate the process for anyone who might not want to try managing codecs manually. Details on the options available are provided via this YouTube video (links to programs are included in the video's description): https://www.youtube.com/watch?v=UoyO812vnIA

The user reported that using two of the tools listed in the video helped them fix the codec issue on their system to restore default Windows functionality.


Other Options
As another option and/or if the codec file(s) is/are not present:

For Windows XP:
1 - Click on Start > Control Panel.
2 - Click on Add hardware icon.
3 - In the Add Hardware Wizard, click on Next button.
4 - Select “Yes, I have already connected the hardware� radio button and then click Next button.
5 - Choose “Add a new hardware device� at the bottom of the list and then click Next.
6 - Select “Install the hardware that I manually select from a list (Advanced)� and click Next.
7 - Select “Sound, video and game controllers� from “Common hardware types� list and click Next.
8 - Select “(Standard system devices)� from “Manufacturer�.
9 - Click on “Have Disk…� button.
10 - Click Browse button in the Install From Disk dialog box. Navigate to folder C:\\Windows\\System32, and then locate mmdriver.inf file. Highlight mmdriver.inf and click Open, then click OK in the Install From Disk dialog box. Click on “Continue Anyway� button if a warning about logo compatibility pops up.
11 - A list of audio codecs supported by mmdriver.inf appears on the Add Hardware Wizard. Select the 'Microsoft ADPCM Audio CODEC' and click on Next to install it.
12 - Restart your system, then launch and test the game.


For Windows Vista/7 (this procedure needs confirmation and testing):
1 - If open, close Windows Media Center.
2 - Click Start and type cmd in the Search programs and files box.
3 - Right-click cmd.exe from the Programs list and click 'Run as administrator'.
4 - Type the following command at the prompt and press Enter
start /wait %windir%\\ehome\\mcupdate.exe –uf
5 - Wait for the command to finish, then close the command prompt window, restart Windows then launch and test the game.



Verify the required registry entries:
If the problem persists and you are familiar with using regedit to view/edit the registry, check to verify that these entries are in the registry:

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\drivers.desc]
"msadp32.acm"="Microsoft ADPCM Audio Codec"

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Drivers32]
"msacm.msadpcm"="msadp32.acm"

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Microsoft\\Windows NT\\CurrentVersion\\Drivers32]
"msacm.msadpcm"="msadp32.acm"



Verify the msadp32.acm file is present in the required folders:
- Make sure the codec file itself, filename msadp32.acm, is present in both the \\System32 and \\SysWOW64 (for Windows 7 64-bit) folders.

The other files listed below, msacm32.dll and msacm32.drv, and the other registry entries listed below may also need to be restored (although this needs further testing to confirm).

Other related registry entries and files that may also need to be checked and corrected/restored:

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Drivers32]
"wavemapper"="msacm32.drv"

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Microsoft\\Windows NT\\CurrentVersion\\Drivers32]
"wavemapper"="msacm32.drv"

Other files also in the \\System32 and \\SysWOW64 (for Windows 7 64-bit) folders:
msacm32.dll
msacm32.drv



Then if the registry entries are present and the codec files are present, but the error occurs, the codec(s) themselves may have been altered or damaged. This procedure may help for Windows 7 64-bit systems (may work for Vista 64-bit, but has not been tested):

1 - Back up the msadp32.acm file in both the \\System32 and \\SysWOW64 folders so you can restore them later if needed.
2 - Download the attached file. It includes original codec files for the ADPCM format in Windows.
3 - Extract the msadp32.acm files from the zip and place them their respectively marked folders.
4 - Restart your system, then launch and test the game.

Please e-mail me with the results of the steps you try, whether the ones available here or other alternatives. I can then update this page as needed.
