What is concerning to me is the fact that often she becomes laser focused on what she is doing and refuses to acknowledge you when you speak to her. I know she's is hearing because she will repeat something I say, but she won't look up and respond to my face.
This reminds me of what my mother has told me about myself when I was a toddler. She would say my name, but I paid no attention. She even referred me to the doctor to check if I could be a little deaf, but my hearing is fine.
I think you should tell your husband that you're going to have her checked just in case, even though you can be worried in the inside (yes, we autistics can say white lies, too

). But don't be worried, anyway. She will be fine!!
