On my MacBook pro 2010 I have Ubuntu 18.04 and the sound is working. By the way, I have to start in terminal mode because the related issue of the graphic card for these 2010 MacBooks.
Then on the same MacBook, I installed Xubuntu because I think the ressources are better used with this GUI and the hybernation is working better as well. Unfortunatelly the sound does not work with Xubuntu; I do not know why.
I start Ubuntu Gnome GUI with:
-> and the sound is working
I start Xubuntu like this:
- cd /etc/init.d
- sudo lightdm start
-> and the sound does not work (I have a virtual audio output)
Do you have some ideas or things I could do to make it work on Xubuntu and why it works on the Gnome UBUNTU GUI ?
