I have read all the solutions in other threads but with no avail, I'm still stuck with no audio. I had no problem like this before in CS3 and I'm currently using/learning CS5.5. I've had no audio at all. However, I can hear audio when I click on the layer that has my mp3 file on their by pressing 0 on the number keypad. But when I go on my main comp I can't hear any audio whatsoever when I press the space bar or when I press the RAM preview button. There is no audio even after I render it and yes, I did click on the audio check box in the audio module that has the lossless link to make sure it is on.
