  Fixed bug 4710 - audio/alsa: avoid configuring hardware parameters with only a single period
  
  Anthony Pesch
  
  The previous code first configured the period size using snd_pcm_hw_par-
  ams_set_period_size_near. Then, it further narrowed the configuration
  space by calling snd_pcm_hw_params_set_buffer_size_near using a buffer
  size of 2 times the _requested_ period size in order to try and get a
  configuration with only 2 periods. If the configured period size was
  larger than the requested size, the second call could inadvertently
  narrow the configuration space to contain only a single period.
  
  Rather than fixing the call to snd_pcm_hw_params_set_buffer_size_near
  to use a size of 2 times the configured period size, the code has been
  changed to use snd_pcm_hw_params_set_periods_min in order to more
  clearly explain the intent.
