Logic Pro X not playing back recorded sounds
I have had and worked with Logic Pro X on my iMac computer since 2013 with no problems. About 3 weeks ago, an audio playback error arose. My recorded material in Logic Pro X along with my compatible MIDI keyboard played back just fine before this incident. Now, whenever I try to play my MIDI keyboard or play a project that I've already made progress on, no sound comes out at all. I can see that the program is actively working and I can also see that the sounds are being made in the program through all of the visual volume colors/representations. It is as if my speakers are the problem. But I am positive that the speakers aren't the problem because they play back all sounds that interact with Google Chrome, Safari, iTunes, the App Store, etc. If anyone can give any legitimate suggestions, I would be very grateful. Thank you.
