Re: [alsa-devel] Why is snd_pcm_hw_params_set_format() not setting the format at all?

When I call snd_pcm_hw_params_set_format() to set up a new format, it seems to call following in order and none of them is setting up the format bit?

snd_pcm_hw_params_set_format() -> snd_pcm_hw_param_set() -> _snd_pcm_hw_param_set() -> snd_mask_refine_set() -> snd_mask_single() + snd_mask_leave()

Please, post or analyze snd_pcm_hw_params_dump() output before and after snd_pcm_hw_params_set_format() call.
