I can confirm this. In 11.04, the HTTP requests being made to retrieve album details are returning a 404. Please find attached an example of the HTTP request/response that Rhythmbox is making. I also run Ubuntu 9.10, this bug occurs there too.
Fixed in Rhythmbox source here: http://git.gnome.org/browse/rhythmbox/commit/?id=1c2f40b58954be25d0ea31d008a6763997f96307 ** Attachment added: "musicbrainz_requestandresponse.txt" https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/791028/+attachment/2280386/+files/musicbrainz_requestandresponse.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791028 Title: Audio Cd's are not automaticaaly identified To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/791028/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
