Subject: Re: 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?

Thanks,
