A few users have been commenting that they have been starting Aerofoil and the settings they have selected in the installer have not been picked up.
This appears to be a "user error".
On install, the installer puts your chosen configuration settings in the program group and startup folder shortcuts for Aerofoil..
Unfortunately the majority of affected users (3 I know of to date) have been starting the Aerofoil.exe in C:\Program Files\Aerofoil instead of with these shortcuts, which of course does not have the chosen settings and starts with everything enabled.
For users who want to run the application manually, please use the shortcut in the "All Programs -> Aerofoil" program group. If you no longer have Aerofoil shortcut icons simply running the installer again will create them (and allow you to reconfigure Aerofoil).
If you are using the shortcuts and still have problems please drop a comment below and an obfuscated email address I can get in contact with you on. Please also verify you are using Aerofoil 1.4.5 by viewing the about box before contacting me (remember if you are updating Aerofoil that you need to exit it before running the new installer).
