Re: [alsa-devel] How to enforce 32bit access?

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?

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
