hi
i have only just bought a behringer mixer and i have installed all the drivers on my laptop and it works fine but when i try to record on to Audacity it is showing just a line event though i have my ipod pluged in

i am using windows 7 os

when i switch recording devices e.g microphone on the laptop it works fine but it dose not work on my mixer

i have only just bought a behringer mixer

Which one? Model number?
