any ideas on how to fix vram for comet lake uhd 630😃

Tried changing the platform id to the ones referred on dortanias guide but I feel like I’ll get a black screeen as i tried them before when i had Windows OS.

It shows as 7mb on Ventura. Also any help on audio? I’ve tried out every layout ID i can and the one I have lastly used only works for headphones. Realtek ALC671
