Photoshop timeline won’t play!

[Its_Bekaaah]

I'm creating a storyboard in Photoshop. The timeline won't play when I click the play icon or press the space bar. However the timeline WILL play if I've muted the audio. When I unmute, the timeline won't play again (it'll play a single frame and stop).
I have restarted photoshop several times and tried messing with the settings but I have been unable to find a consistent fix. Any idea what's going on?

I've been having the same problem but I don't know how to fix it.

Well it worked again but only cause I just didnt use it for a long while so it must have reset or something somehow. But it happened again and so I closed it out yet it still isn't working?

Actually so far, it seems that quitting photoshop, opening it back up, making sure the timeline is there before opening the animation/storyboard(etc.) document is opened, and then opening the document seemed to work? Also maybe get rid pf the timeline before quitting photoshop?
