oggdec not able to decode multitrack ogg files
OggDec 1.0.1 - provided by vorbis-tools (1.1.1-15ubuntu0.1) - is not able to decode multitrack ogg files. Here is a sample I recorded using idjc-7.5.4
lavish@daw:~$ oggdec -o multitrack_sample.wav multitrack_sample.oga

I managed to decode it with ogg123:
lavish@daw:~$ ogg123 -d wav -f multitrack_sample.wav multitrack_sample.oga
Audio Device: WAV file output
Playing: multitrack_sample.oga

Done.
Thanks for your software, keep up the good work!
