David [Hinds],

On a related topic, I've pulled down your stuff at sourceforge and we
are using it for our 2.4 build. Is this the baest place or do you have
somewhere more recent and is this the list to report bugs? We have seen
some problems with IBM thinkpads with DSP devices having some issues
(like the volume control doesn't work right on 2.4). Most are just
annoyances and what I would classify as level IV bugs (very
non-critical).

Thanks,

Jeff
