Hey I'm having this problem tonight:
Hotkeys for sound up/down/on/off (Fn+F11/F12/F10) work without problems on root account, but for any non-root user I only get volume bar with 0% and nothing is changing.
Just in case - I have sound for non-root users but can change volume only by using Mixer, and other hotkeys like LCD on/off work without problems.
Thanks for help
