  Fixed microphone randomly stop working
  
  WASAPI_WaitDevice is used for audio playback and capture, but needs to
  behave slighty different.
  For playback `GetCurrentPadding` returns the padding which is already
  queued, so WaitDevice should return when buffer length falls below the
  buffer threshold (`maxpadding`).
  For capture `GetCurrentPadding` returns the available data which can be
  read, so WaitDevice can return as soon as any data is available.
  
  In the old implementation WaitDevice could suddenly hang. This is
  because on many capture devices the buffer (`padding`) wasn't filled
  fast enough to surpass `maxpadding`. But if at one point (due to unlucky
  timing) more than maxpadding frames were available, WaitDevice would not
  return anymore.
  
  Issue #3234 is probably related to this.
