Process ID: CAudioFilterAgent.exe, System Configuration ID: Conexant High Definition Audio Filtr Agent && SmartAudio Control Panel application. I ended the process while watching a movie, and nothing happened. I stopped the startup applications and restarted, nothing seemes different. I would, and did, remove these items because they use memory.
