Solved on my side. I've been updating distributions using update-manager for past 3 years. Booting 8.10 live-cd and seeing keys working properly I reinstalled the system (but kept /home directory).
After booting into freshly installed ubuntu, keys were still not working. Then I checked "Keyboard Shortcuts" and was able to fix "Volume mute/down/up" keys from there. -- Sound keys do not work on HP Compaq nx8220 (regression) https://bugs.launchpad.net/bugs/290636 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
