MacBookPro13,2 audio, camera, wifi - present status

MacBookPro 13,2
Ubuntu 24.04.2 LTS (clean install without MacOS)
Touchbar version

Hi,

I have previously installed Ubuntu to 3 different mac’s without any major issues. I decided to buy to my son MacBookPro 13,2 because it was dirty cheap. I of course thought that to install Ubuntu to it would be a breeze. How wrong I was.

I have installed Ubuntu to it successfully, but few issues are persistent.

No sound
No wifi
No camera
No touchbar

There might be other issues, but these four are the ones that I would like to solve first.

I have read

and at least camera and touchbar should work. I have tried different suggestions how to get those to work, but no success. Usually I get notices that repos are outdated or similar errors with codes that I have been able to find. Sound and wifi might be not possible, but I would like to know latest situation with those. Also, if sound and wifi are not possible to get to work then do you have any suggestions for plug-in ware to buy?

Any help or news with these issues?

Thank you!

Ok, I have studied and search lots of stuff and here is how I got sound working, speakers and headphone:

git clone https://github.com/egorenar/snd-hda-codec-cs8409.git
cd snd-hda-codec-cs8409
make
sudo make install
reboot

At least one done. Hope it stays kernel updates too.

Next issue solved, Wifi. I was able to get it to work by following method:

I did not need this step, most probably old stuff, but just in case:
1.
sudo apt-get purge bcmwl-kernel-source
sudo apt update
sudo update-pciids
sudo apt install firmware-b43-installer
sudo reboot

I started from here:
2. How I resolved connectivity issues
Downloaded brcmfmac43602-pcie.txt here: https://bugzilla.kernel.org/attachment.cgi?id=285753
Opened in Text Editor
Changed the following lines:
macaddr=xx:xx:xx:xx:xx:xx
ccode=X3
regrev=15

to

macaddr=00:90:4c:0d:f4:3e
ccode=0
regrev=1

In Terminal:
sudo cp ~/Downloads/brcmfmac43602-pcie.txt /lib/firmware/brcm/
sudo reboot

Wifi works!

Still

No camera
No touchbar

But now is enough with this. I come back to this later. Of course, if anyone has any suggestions, I am more then happy to hear.
