Dell Latitude 3310 macOS Sonoma Problems (Display & Audio)

Over the past few days I have been working at getting this laptop (Dell lattitude 3310) working as best as I can while running macOS Sonoma (14.2.1) However, there are a few problems that no matter how much research I do, I cannot find and fixes that work, so have decided to make this post.

My current problems:-

  • Crackly audio through audio jack (speakers and bluetooth work fine)
  • Display not waking when laptop lid opened. (If I put the laptop to sleep manually and the tap the keyboard, everything works as it should) (Seems to work most of the time if I leave the laptop shut for a while before opening it back up.)
  • No display brightness control (The slider is greyed out, my keyboard shortcuts don't make any popups show either)

My Laptop:

  • Dell Latitude 3310
  • Intel i5-8265U
  • Intel UHD620
  • 8GB DDR4
  • 256gb nvme ssd

Thanks for any help in advance.
