I'm having weird effects with sound in vlc 0.8.1, it keeps speeding up
and slowing down. Does ogg123 have a similar issue. A possible cause is
that when new headers are received the player may very well reset the
audio interface to the settings in the new header and this could cause
For a test, try downloading the stream to file then play the file back.
I haven't used JORBIS myself

some players are known to have problems with chained bitstreams, my vlc
seems ok with the chaining but screws up on sound output.
There hasn't been much change in the way ogg is handled in the later
releases of icecast-kh, the headers are still handled the same way.
