This is surprising. Audacious _appears_ to have a syslog parser of some
sort:
http://sources.debian.net/src/audacious/3.7.2-1/src/libaudqt/log-inspector.cc/
I can't find any documentation _why_, and I gave up trying to find out
which files it actually reads. (A little C++ goes a long way towards
obfuscating the point of code... sigh.)
I think I'd add the 'deny' rules. I don't know why an audio player needs
this and if it breaks the audio player, I'd pick a different player.

The same reason applies here too! :)

You should add a rule like:
/usr/bin/audacious Pxr,
You have a profile for audacious and you want it to be used. So use Px, to
ask for the specific audacious profile.
The rule you proposed here would actually not use your profile at all.

There are no plans to update to newer versions of Audacious. Not many
packages get automatic next-version updates: firefox, chromium-browser,
mysql, mariadb, maybe a handful of others. It's safe to say those five are
probably the majority of whole-new-version updates.
If there's a compelling reason to do an update you can look into
performing a Stable Release Update:
