Have you initialized and updated the db?

Strange, it sounds like something is broken with your encoder. FYI,
Vorbis, together with mp3, are the most supported lossy codecs in
Rockox.

I don't use Sound Juicer, so I am not sure if it is broken. I use a
version of oggenc linked against the Aotuv branch of libvorbis:

From the commandline and with grip.

This might be your problem. Ogg Vorbis files doesn't use id3 tags, but
Vorbis comments. Some bad programs will try to embed id3 tags in the Ogg
container, which will produce broken files.

I see that you are using an e260. You might be interested in my
unofficial builds for the e200 target located here:
