I suffer the same symptoms: Volume hot keys don't change the volume.
I have 2 soundscards, and the hotkey is actually changing the volume for the wrong soundcard! I verified this by opening the mixer application for my 'onboard soundcard', which isn't connected.
the hotkeys should respect ~/.asoundrc for selecting the right 'default' soundcard and not just using the first one in the system.
