You might want to look at Christopher Newport in VA. They have a good program and do not require an audition. Plymouth State University in NH requires an audition, but may accept a video submission. Keene State, also in NH, has a new faculty member with a strong background in Musical Theatre, and they do musicals on a regular basis. Keene state does not require an audition.
Will you audition for Muhlenberg? They have an audition for scholarships. I believe they take demonstrated interest into consideration with admissions decisions.
Do you have a few non-audition financial and academic safety schools on your list that you would be happy to attend if admitted?
As others have said, just about no one passes all of their prescreens, or is admitted to all of their schools. Try not to let the early prescreens results from a few schools discourage you. Make sure that you have a balanced list of schools that you like.
Hang in!
