I have an up-to-date Macbook Air on which the sound no longer works.
I had installed Soundflowerbed on it, and for a long time everything was working fine until a couple of weeks ago when it started to not work after a while.
Then it stopped completely.
I uninstalled Soundflowerbed, reset using:
- command + alt + P + R, and
- shift + ctrl + alt
but, still the sound does not work.
The Sound devices view look like this:

What can I do to get the sound back? I did the hardware tests (pressing D while booting), and there are no issues.
Also, I am pretty sure it is not a hardware issue.
Is there a way to reinstall the sound drivers or something like that?
I did a fresh install, reinstalling the whole system and the sound worked for one day, and now I have the same issue...
