“Failed to Initialize SmartAudio.The Application will Now Exit“ error
on Windows

The same error "Failed to initialize SmartAudio.The application will now exit“ pops up every time I launch the computer. And sometimes my sound disappears, do you know I can fix it?

“Failed to initialize SmartAudio.The application will now exit” error is associated with Conexant Audio Filter Agent, which is an integral part of Conexant High Definition Audio. It is preinstalled on the computers of certain brands. The error message might appear if users have updated their sound drivers recently or installed additional ones. Therefore, it may result in a certain mismatch between functioning drivers. Users may also notice that cafedebug.txt or cafedebug.exe file is running in Task Manager at startup.
