ogg123 chops 11, 13 or more channel vorbis audio
I do a lot of work with multichannel audio. Most 8, 10, 12 or 16 channels.
Recently I am using 11 channel vorbis files and find ogg123 garbles the playback. Sound like every 10th second a different channel is being played.
Same happens for 11, 13, 15 channels! Looks like there is a problem with odd numbers of channels above 10. 9 is fine!
The problem occurs with ogg123 version 1.4.0. when playing back to an ALSA device. I have checked the problem is repeatable under following variations: 5 Different ALSA devices 2 Different Linux distributions 2 Different kernel versions
The multichannel audio files can be played by mplayer to ALSA without problems.
