A bug you may have had, and how to get around it.

[Phil The Fleshdemon]

This issue may have been solved in the most recent update, but there was this bug I kept getting where often during playback and even recording, but specifically playback, I sometimes would press play just to be stuck with no sound while it would not allow you to stop, close or do anything unless you (A: force closed the program or (B: had bandlab assistant running and you could quit that app which would also close cakewalk. 

Here is what to do if you ever encounter this situation. Turn on and off any tracks Input Echo button. It will resume playing with sound and everything will function properly again. Hope that helps!
