  73 <p>
  74 HalAudioSrc allows access to input of sound devices by specifying the
  75 corresponding persistent Unique Device Id (UDI) from the Hardware Abstraction
  76 Layer (HAL) in the <a class="link" href="gst-plugins-good-plugins-halaudiosrc.html#GstHalAudioSrc--udi" title='The "udi" property'><span class="type">"udi"</span></a> property.
  77 It currently always embeds alsasrc or osssrc as HAL doesn't support other
  78 sound systems yet. You can also specify the UDI of a device that has ALSA or
  79 OSS subdevices. If both are present ALSA is preferred.
