.I started a kenitic type project with CS6 and have now just got CC and am trying to complete the project with the Cloud CS. I've imported my mp3 file and have brought in my type layers. But when I try to hear the audio, I get nothing. I've tried the ram preview...nothing. I've tried the (.) on the number pad as well as using Shift/ and moving the scrubber. Still nothing. I have the original mp3 file on my desk top and can hear it fine from there. There is no interactivity with the audio panel...it's kind of dulled down. Do anyone have any thoughts?
MP3 files are inappropriate for production work. Convert your MP3 to an uncompressed WAV or AIF file and reimport.
Also, check After Effects Preferences/Audio Hardware and Audio Output Mapping, to ensure your standard audio outputs are being used.
I just did that and I re-imported the file and it's working.
