Timeline audio all of a sudden went muted...
There I was, just minding my own business editing in my timeline...when all of a sudden no audio playback whatsoever. No action in the meters. Waveforms are still there. No media disconnected. Restarting app/comp does nothing. Copying contents from one sequence over to new sequence brings it back (no changes in sequence settings whatsoever) but I'm still baffled as to what happened in the first place.
Is there some hidden shortcut for muting audio tracks? No tracks appear muted.
This has happened twice this week (different computers, different projects) and so I'm very curious what happened so I can keep it from occurring.
