When you say it doesn't match, what do you mean?
Are you doing your preview by pressing 0 or .?
Is your CS6 been updated to version 11.0.4?
What version of Windows did you install?
What are your audio preferences?
What is your audio hardware?
What I say when it doesn't match is that when i put a clip to start at the beginning of a beat on the waveform the beat is actually behind the waveform where it shows the beat of the song so the clip i put to start at the beginning of the beat actually starts somewhere else.
I am using RAM preview.
I have version 11.0.
I have Windows 10.
My audio preferences are fine.
My sound card is the NVIDIA Virtual Audio Device (Wave Extensible) (WDM)/NVIDIA High Definition Audio
You are missing several bug fix updates. CS6 is up to version 11.0.4
Also, that version of After Effects is not officially supported for Windows 10. This may be an issue you have to deal with if you don't want to get a current version of AE.
