Why doesn't the Play button Play in Premiere CS6? I am editing a video in Adobe Premiere Pro CS6 on a 2012 MacBook Pro with the Intel HD Graphics 4000. Sometimes the play button does not play the footage anymore, I can press the button but nothing happens. Do you have any suggestions for a solution?



EDIT

I have figured something out.

Last time I moved my PC, I had to re-plug-in all my stuff. Mic, USB for the external sound hard drive and so on.

Then I started up CS5.5 Premiere Pro and, with all preferences as usual, nothing worked. I pressed the "Play" button and nothing happened.

After a while, I found out that the Default Settings for the Sound in- and output works only but my UX24 Asio driver wasn't accepted anymore in a way that I wasn't able to use the Play button.

Well, I closed CS5.5 and then re-re-pluged-in all my Stuff.  Then I opened CS5.5 and selected Asio Ux24 (my soundcard) and everything worked again. Don't ask me why it accepted it this time. Maybe you have to plug in everything in a certain order. Please let me know if that is the case.

My problem now:

I moved my PC again and I face the same problem.  So I did everything I did as described before, but it didn't work.

The last point, and I quote here "Go to Preferences -> Audio Hardware and change Default Device to Built-in Output. Do the same in Preferences -> Audio Output mapping.", was all set. Everything right, as usual. Re-Pluging in the hardware didn't work and re-selecting, restarting didn't work either.

I need support and help, because there are people waiting for me to make videos.
Thanks for any answers.
Okay, this worked for me:


Re-Plug-in ALL your External Sound-Hardware.
Open your Sound Menu from Windows and set your Microphone to your current one. (For me it was the external Soundcard)
Now Open up Premiere Pro and set everything on your Preferences as previously stated.
Save your Current Sequenz/Project. Close premiere.
Reboot your PC.
Check your Sound Options in Windows, if everything is set right.
Open Premiere and check again, if your Prefences are still in (everything should be in order)
Now hit play.
If the Re-plugin doesnt work, use different USB slots :)


Hope I could help you.
