Well, to be honest, I don't know if I have that patch. I couldn't find in the patch mail message in which kernel it was included. I only found references to 4.2 and 4.1 I have this kernel: $ uname -a Linux poseidon 3.19.0-20-generic #20-Ubuntu SMP Fri May 29 10:10:47 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux I decided to update, and see what the result was. Apparently, sound started working again for all users, except for myself. That's why I didn't notice it right away, that the sound worked again. In my user account it didn't work. And I even had no sound device to choose from in the sound setting dialog box. After some googling, I decided to try this, and it worked: $ rm -r ~/.config/pulse/* And then i copied the pulse config from a user where the sound did work. Rebooted... And my sound works again. Thanks for everything.
