Great, a person trying 64bit CPU for audio! I have
lots of questions.
First, what do you mean by "not masked for AMD64". Is that a compile
flag in some apps?
its packages masked via the portage profile. gentoo has a few safeguards against the
system being 'too' bleeding-edge. once its marked as working and tested a package
is unmasked by adding to the KEYWORDS of its ebuild, usually for ~arch first, then arch.
none of the audio apps you mention below are masked, at least not for ~amd64. give them a
go..
as necessary you can override by echoing the name to a file in /etc/portage if noone got
around to testing it..
had to build, and your experiences/problems with them?
The primary ones
like jack, qjackctl, drivers, etc. would be very interesting to learn
about as well as the major ones like Rosegarden, ardour, etc..
