I did get this problem on Edgy and also on Gentoo with Totem and Gstreamer.
Upstream report which had the patch fixed it: http://bugzilla.gnome.org/show_bug.cgi?id=348002 -- AC3 videos sound WAY too soft https://launchpad.net/bugs/39275 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
