LibAtrac9 defines six channel configurations but indexed the table with all eight values of the 3-bit field, so indices 6 and 7 read past it and initialized a decoder from the bytes that follow. The config data check now fails for them, which sceAjmDecAt9ParseConfigData, AJM initialization, libSceAudiodec and NGS2 already report as invalid config data.
