I am an Intro maker, and after effects cc 2015 has been acting up ALOT lately... for example. As im Prerendering, No audio would play, then it wouldnt play in realtime. Also, it would lag the audio when im watching the prerender, also, as the prerender is playing i press the Star on my keyboard to make a marker, then it would lag an stop playing in realtime
I Have After Effects CC 2015
Nobody can tell you anything without proper system info or other technical details. That said, CC 2015 is a bust and complete garbage. that's all I'm ever going to asay about the matter.
