No audio playing in preview

I have the audio icons checked in timeline and in preview (obviously), I have un-checked in preferences to mute the audio if playback is not real time, I have cache before playback, I meddled with audio hardware and all seems to be set to correct output. Everything works fine on another computer, but one I work on now, plays sound in any other app, including Premiere Pro. I have no clue what to do really. I re-installed AE, turned computer off and on, nothing works. Sound gets rendered, so program has to see it, but I obviously can't work without hearing it in the project. I tried importing many different files to new projects, problem persists.
