There is a known major bug with libvorbis-1.1.0's encoding quality and GCC 4.x when GCC does any optimization whatsoever. The Oggs encoded with this broken libvorbis sound really, /really/ bad. I can provide samples of the difference between a qual 3 ogg in the broken encoder and the same song encoded with a non-broken one. Xiph discovered this issue and fixed it in libvorbis-1.1.2, which has been ~x86 for a while. It would be nice to not have our users encoding lots and lots of really crappy Oggs, whether through a backport of the patch that fixes the bug or a (seemingly safe; I reencoded something like 1000 Oggs overnight to replace ones that had the skeevy sound) version bump.
May be it's time to have 1.1.2 stabilized. In bug #149855 , Flameeyes stated that he doesn't want to stabilize it unless there is a reason. Maybe this bug is the reason. libvorbis 1.1.1 & 1.1.2 are mainly bugfix releases, see: http://lists.xiph.org/pipermail/vorbis/2005-June/025826.html http://lists.xiph.org/pipermail/vorbis/2005-November/026129.html So, arch teams, that's up to your decision now :)

Stable on ppc
libvorbis-1.1.2 USE="-aotuv" looks good for me too on x86. i'm still able to play ogg files using audacious-1.2.1 and the files i've just ripped from a cd to ogg using sound-juicer-2.14.4 are fine.
Playing on x86
sparc stable.
I've been running with this version of the library ever since I posted the bug with no problems whatsoever, encoding tracks, listening to them via XMMS and on the command line, and so on. I'm running x86.
Stable for HPPA.
ppc64 stable
Alpha stable.
amd64 stable
Marked stable on MIPS.
