I can confirm this bug on Hardy Beta AMD64 with all available updates (kernel 2.6.24-15), on Uniwill M31E. Alsa mixer is not available, and in avaliable mixers there is no HDA Intel (Alsa mixer), only Realtek ALC861 (OSS Mixer) for onboard audio. I cannot effectively set volume in GUI.
Running exactly same system booted with vanilla kernel 2.6.24-3 fixes these problems - so i think alsa modules in Hardy's kernel are somewhat broken.
