I have recently installed LJ2 and all working great. However, the audio analyser seems to be behaving very strangely. There is a lag that gets bigger and bigger between the actual audio and it tripggering the analyser. It starts off bang on the money, and the latency gets worse and worse after that.
1) Computer hardware drivers current? If not then the latest drivers are (mostly always) available for download at the manufacturer website.
2) Could it possibly be an audio feedback loop of some kind? Are you using the audio for any other software on your computer? If it were me, I might try muting all the computer systems audio mixer inputs and outputs except the audio input for Light Jockey audio analyzer.
