I have a new Macbook Pro retina (late 2013 model) running Ubuntu 13.10. I can't get the sound to work. I have tried the solution here , but it's not changing anything. I also tried the following series of commands, but they don't change anything, either:
sudo apt-get remove --purge alsa-base sudo apt-get remove --purge pulseaudio sudo apt-get install alsa-base sudo apt-get install pulseaudio sudo alsa force-reload
When I start the computer and the login screen appears, I hear one sound - the sound Ubuntu usually makes when there's an error. After I log in, however, I can't hear anything again. The sound works perfectly on OSX - it's only Ubuntu that seems to be having this problem. Is there anything else I can try to get the sound to work?
