Having absolutely the same problem.

[evyscr@tkv alsa]$ rpm -q libalsa2
libalsa2-0.9.0rc7-alt1


From /usr/include/alsa/pcm.h

  int snd_pcm_hw_params_get_period_size(const snd_pcm_hw_params_t *params,

__attribute__ ((weak, alias ("__snd_pcm_hw_params_get_period_size")));

  snd_pcm_sframes_t snd_pcm_hw_params_get_period_size(const snd_pcm_hw_params_t

Thanks, evyscr.
