DSDSourceFilter.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like DSDSourceFilter.ax, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AudioProfiler.exe - to follow. These files were created so that multiple programs (eg. Media Player Codec Pack) could share the same DSDSourceFilter.ax file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared AX file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when DSDSourceFilter.ax is attempted to be loaded either when Media Player Codec Pack is starting up, or in some cases already running. Some of the most common DSDSourceFilter.ax errors include:
- Access Violation at address - DSDSourceFilter.ax.
- DSDSourceFilter.ax could not be found.
- Cannot find C:\Windows\SysWOW64\DSDSourceFilter.ax.
- Cannot register DSDSourceFilter.ax.
- Cannot start Media Player Codec Pack. A required component is missing: DSDSourceFilter.ax. Please install Media Player Codec Pack again.
- Failed to load DSDSourceFilter.ax.
- The application has failed to start because DSDSourceFilter.ax was not found.
- The file DSDSourceFilter.ax is missing or corrupt.
- This application failed to start because DSDSourceFilter.ax was not found. Re-installing the application may fix this problem.
Your DSDSourceFilter.ax file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Media Player Codec Pack), or deleted by a malware infection. Furthermore, DSDSourceFilter.ax file corruption could be caused from a power outage when loading Media Player Codec Pack, system crash while loading DSDSourceFilter.ax, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
