desperate for NOOB instructions. No webcam or Microphone on Macbook pro with ubuntu installed

I have Ubuntu 20.4 installed on a partition on my Mac. So far so good. except for the internal Mic and camera are not working. I have been trying to fix it by installing drivers, however the instructions I have found are already above my knowledge. When describing edit the modules and commands like "Make" I recieve return messages in the command line that what I have typed in incorrect, unrecgonised ect.

Can someone please help or point me to a step by step guide for someone who is really trying to learn Ubuntu what I need to do to get the webcam and Mic activated.

I finally decided I need to get off Mac Os and move to Ubuntu. The Mac Os is out-dating itself and becoming obsolete faster than I can afford. the webcam and Mic are crucial to this new adventure. please help!

Treat this as two problems: Camera and Microphone.
I can, given the lack of information in your question, (Read https://askubuntu.com/help/how-to-ask and https://askubuntu.com/help/formatting ) offer a possible solution. What does sudo lshw -short tell you? Read man lshw sudo.

Many device access problems can be resolved through group membership changes.

Your $device is possibly /dev/video*.

Specifically, if ls -l $device shows that the group permissions (the second "rwx" triplet) is "rw" (e.g."-rw-rw----"), then, adding oneself to the group that owns the device will grant rw access.

Here's how:

# change to your device name 
device="/dev/dvdrw"
sudo adduser $USER $(stat -c "%G" $device)

This allows you membership in the group that can rw the device, but there is one more step.

To make all your processes members of the new group, logout and login. Group memberships are set up at login time.

To create a single process in the new group (for testing, prior to logout/login):

newgrp $(stat -c "%G" $device)  

or, just type the group name. See man newgrp.
