Hi ALSA devs,
meanwhile I tried to put a constraint on SNDRV_PCM_HW_PARAM_FRAME_BITS by the use of snd_pcm_hw_constraint_minmax() function with min=32 and max=32, but still no success - the ALSA Library still makes 16bit accesses, when playing mono (1 channel) files.
Any ideas?
Could you show the chain of plugins via aplay -v ? I'm not sure which plugin requires S16. Possibly, the rate converter.

Therefore my question is:
In my driver for the controller, how do I tell ALSA, that it is only allowed to write in 32bit quantities? Is this possible at all? Or do I have to use a special .asoundrc file?
Thanks, Joachim
