You could've said to her "I've been saying hi to you every morning but you've never heard me."
What does she expect you to do? She doesn't even look at you when you come in, right? Does she want you to tap her on the shoulder or wave your hand in front of her face to get her attention to say hi? Maybe you can pull her headphones off one ear and say hi with a big smile.
That is what I feel like doing!
If I wasn't worried about tension affecting our work, I'd plainly ask her, "Why didn't you say good morning to me if it's so important to you?" Alas, I have to work with her so...
