Comment (by mac20xx@…):
To me its not a problem of byte conversation but a problem of bit
location.
When using SND_PCM_FORMAT_S24 alsa fetches data from bits 0-24,
when using SND_PCM_FORMAT_S32 from bits 8-31.
For testing create a 24bit wave file: sox input.flac -3 24bit.wav
This should play fine with aplay
Turn volume to zero, start playback in mythmusic and then slowly increase
volume.
On my system I only hear very loud white noise without the changes I
suggested.
