you should be able to here the audio on a ram preview, if needed you can always shorten your work area to quickly render our small sections you are working on… hit the ‘b’ key to set the begining and the ‘n’ key set the end of the work area — note make suer you set the workarea back to the full duration of the comp (or area you want to render) otherwise you will only render the workarea.
you can also hit the decimal point on the numeric keypad to hear just the audio. this is useful when used in conjunction with hitting the asterisk on the numeric keypad to add markers to your layer at the points that something needs to happen.
also you can hold the command (mac) or control (pc) key down while scrubbing thru the timeline to hear audio as you scrub.
there is also a wave form that you can view (not the greatest, but its there). twirl down the attirbutes for your audio layer, then twirl the audio, and then waveform. if you zoom in on the timeline you’ll be able to see the waveform better, but it’s still not as useful as it could be.
