I just tried that and it works on my platform. Meanwhile I reproduced
a song I recorded two wavs.

Unfortunately that didn't help, I hear nothing from the speakers :(
I have a Radxa Rock2 Square board, by chance, do you have a git tree
containing the patches to enable the i2s sound for radxa so I can
