Audio not working in after affect effect CC
I have checked all the option for the audio to play when preview.
1) Audio "ON" in Comp

2) Audio "ON" in preview

3)Audio selection in preference --> Audio hardware (no device class section)

I do not have option as device class (below image is from the youtube for reference)

What could be the problem for not have the devie class section? How can I correct it?
