You have only one track highlited, right?
(you won't hear a track if it is getting recorded over)

What soundcard? It is most likely a soundcard setting..
maybe even the 'full duplex' setting in the preferences area of RB audio
(Prefs button or 'options-preferences-audio')
It should be on..


I do not work here, but the benefits are still awesome
