I also had the same problem. I run Kubuntu 8.10 on dell inspiron 6400. the volume hot keys did not seem to work. I noticed that when they are pressed the PCM channel volume goes up and down.
So I just selected the PCM channel as the master channel, cranked up the front channel to full...now the hot keys work perfect!!
