[alsa-devel] [ASoC] Sample format non available

Dear list,
I'm currently implementing a ASoC solution for a custom chip and I've
written a codec, I2S, PCM, and machine driver. However, when using
aplay I get the following error (requested format was: 2):
root:~# aplay -M -D hw:0,0 test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: set_params:906: Sample format non available
However, I've told each piece involved, that it is capable of playing
S16_LE. So I don't know what I am missing here?
Should I provide more debugging output like RULES_DEBUG output from
sound/core/pcm_native.c?
