Aside from the sound problems mentioned above, many things are
working. I am mostly using Pure Data (PD) and Rosegarden with DSSI
plugins, and there was one critical change:
I had to change the first line in /etc/hosts from
::1 localhost.localdomain localhost
to
127.0.0.1 localhost.localdomain localhost
Without this change, the WhySynth editor GUI would not come
up on the screen, even though it was running. It is said that
liblo needs to be able to resolve the hostname for Open Sound
Control (OSC) linkage between the host and GUI, and it apparently
can't deal with the newer '::1' notation, which is said to be for IPv6
(Internet Protocol, version 6). I only had this problem on my
notebook because there I did a fresh install of FC6. On my desktop
machine, in contrast, I upgraded from FC5 to FC6, and
/etc/hosts was evidently left alone (it still has the old
style localhost entry).
Initially, pd produced no sound. It evidently did not detect
the jack audio server and defaulted to 0 audio output channels. This
was fixable under the ``Media / Audio settings 
'' menu item. For
the future, I added various flags to my /.pdrc init file:
-jack -r 48000 -audiooutdev 1 -outchannels 2 \
-path /l/pd/externs \
-path /usr/lib/pd/extra \
-path /usr/lib/pd/extra/cyclone \
-path /usr/lib/pd/extra/oscx \
-path /usr/lib/pd/extra/iemlib \
-path /usr/lib/pd/doc/5.reference/iemhelp \
-path /usr/lib/pd/doc/5.reference
The various added -path directories have evolved over the
years -- I don't know if they're all still needed. The directory
/l/p/pd/externs/ contains my own pd externs. I believe all the
others come standard with ``pd extended'' as installed when the Planet
CCRMA distribution is installed.
