This is definetly a Gnome issue. As KDE has no problem at all detecting
the PCM. The problem here is that with the Thinkpad T61 & some other
newer laptops the sound  card no longer has a hardware mixer (otherwise
know as "Master"), now they only have "PCM".

KDE seems to be able to handle this fine. I confirmed this by booting up
Kubuntu 7.10 live cd on my Thinkpad T61 and when I pressed the up and
down volume keys, they changed the volume of "PCM". Just worked out of
the box.

I have been looking through the Gnome code base and I see places where
if it does not detect "Master" it should fall back and try "PCM" , but
this does not appear to work.
