No sound through headphones
new user. yesterday i loaded a new project to basically record my voice over a backing track. loaded the btrax and created a new track for my voice. equipment wise i have a mic & phones plugged into an interface which is connected to mac via usb. all knobs and switches set appropriately and sound came through phones. however, today i am trying the same thing and cannot get any sound through phones or through mac either. not sure why this is happening - hopefully its something straight forward and simple - can anyone help please?
MacBookPro, Mac OS X (10.6.4)
