software (even a few audio managers) do not properly handle audio management. Instead they just adjust the system mixer and unmute the line in to create a loopback. This causes more problems then I can describe but the short version is to undo what they broke and then everything should work.
* Open the sound control panel
* click recording devices
* right click the device and select properties
* uncheck listen to this device on the listen tab
* open the recording mixer
* check the mute checkbox next to the device
Most importantly...dont run om and rr at the same time...rr will break things again
