Latest AE. Audio works on an empty sequence, then as soon as you add up effects, it stops playing.
If I create a new empty sequence, and then paste audio there, within the same project, it plays again.
Even if you give it time to render, it would play a first milisecond of audio and then go silent again while the image keeps playing.
All the Audio playback features are enabled. All the audio hardware configurations are correct. Tried rebooting.
Nothing seems to help.
