What sort of audio is in your comp? If it's mp3, try converting it to WAV or AIFF outside of AE and replacing it.
Also, what (exact) version number of AE are you using? 11.0.1? 9.0.2?
It was .mp3 then I converted it to .wav using format factory.
and Im running 188.8.131.52
just updated to 11.0.2 and still nothing
I click Render and it just says rendering but nothing changes
not even time elapsed or est. remaining
just stays on compressing and writing and my ram used doesnt even start going up
Can you do a RAM preview with sound?
Ooh, wait. Can you render to an audio format? If so, you can just piece them together in your NLE.
