FC6 and Planet CCRMA on the HP Pavilion Notebook

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 $\ldots$'' 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.
