I think the reason you're having a problem with audio learning is because you perhaps need to something tangible to connect it to. What are you doing while listening to audio lecture? Are you looking at a picture? Are you taking notes?
Audio lectures are NOT meant to be a "listen and regurgitate and I got it" type thing. It is nothing more than a means of GIVING you the information. Are there words associated with the audio that you can copy and paste under a picture you find from google?
Anatomy is anatomy is anatomy is anatomy. It is always going to be anatomy, and therefore no matter what image you find on the internet or resource you find, it is going to be a great resource to use, as long as you learn it, it does not matter how you learned it.
I suggest you follow along with the audio lectures and only use the words as a tool, do not plan on learning from these words. you should be taking their words, converting it into something that makes sense to you, and reviewing it, over, and over, and over.
I like Anki. I only use Anki. It's the only study resource I've used in all of medical school. If I don't like a picture that my professors give us in a power point, I will google my own, and then I will use the "Occlusion" feature to blank out the important things I need to know and test myself that way. I like verbal, but like you, unless I am reading it in my own head or using their words to associate to a picture, it's just going to go in one ear and out the other.
It's hard because you are not really telling us exactly what resources your school has offered you. For me, I will make every single Powerpoint slide into an Anki card. I will then make a title of what I think I need to know on this card, then I will press Play on the lecture, listen to what they said for that slide, then I'll pause the lecture again. I will take their words and use it to reformat how the words in the PPT were displayed, take out the useless garbage, and keep the stuff they said was important, move on, rinse and repeat. If it is something they said verbally that you should 100% know, I make a whole new anki card just for that. It will still be in the original, but I will have a more targeted card, because at the end of the day, these professors are writing the exams and know what is important.
TLDR:
Figure out how you learn, then convert their words into that, then study it over and over and over.
