Created attachment 414238 [details] [diff] [review] patch The issue in bug 481601 was fixed in libfishsound upstream without the use of vorbis_dsp_init, and ended up in the mozilla tree with bug 480521. Which means the part in libvorbis is now of no use, and an unnecessary diversion from upstream.
This has already been removed from the 1.9.2 branch and trunk (see bug 518952). There's probably not much point taking this particular patch on 1.9.1.
