My SmartAudio stopped working and I couldn't find anything about what to do to fix it.
It took a lone time to find the SmartAudio folder so here's where you should look.
C:> users > (your name or the name of the computer, whatever) > AppData > Local > Conexant > SmartAudio
When you find the SmartAudio folder right click on it and select Properties then cilck on the Previous Versions tab at the top.
Select an earlier date for the folder and click the "Restore" button. This fixed the problem for me.
