Ram Preview Not Playing

[dustino64420197]

My ram preview just sits there as if it's playing but doesn't move. I can click and drag through the animation but it won't play, despite the preview button appearing like a square.

I can typically use after effects and ram preview for a few minutes but then it just gets stuck. What gives?

FIXED. My external audio card (traktor kontrol s4) had crashed and wasn't allowing anything to play, both in youtube and in AE.

How did you fix it?

Change your Default Output to something else. Change it back if you know it's correct.
