This conformant component accepts raw PCM audio, and outputs this data
using platform-specific audio output devices. Control of these
platform-specific devices is outside the scope of IL. By default, when
connected to a clock component, it will act as a clock reference. The
time scale of the clock is respected, and when not normal speed no audio
will be played and no reference times will be advertised to the clock.
| Port | Index | Notes | 
| 100 | OMX_IndexParamPortDefinition | Supports setting the port to PCM or DDP data. | 
| OMX_IndexParamAudioPortFormat | Supports setting the port format to PCM unencoded audio, or DDP
  encoded data. | 
| OMX_IndexParamAudioPcm | nChannels must be between 1 and 8.
  eNumData must be OMX_NumericalDataSigned.
  eEndian must be OMX_EndianLittle or OMX_EndianBig.
  bInterleaved must be OMX_TRUE.
  nBitPerSample must be 16 or 32.
  nSamplingRate must be greater than or equal to 8000 but
  less than or equal to 192000.
  ePCMMode must be OMX_AUDIO_PCMModeLinear. | 
| OMX_IndexParamAudioDdp | Query / set the DDP format of this port.
  nSamplingRate must be 32000, 44100 or 48000. | 
| OMX_IndexParamAudioDts | Query / set the DTS format of this port. | 
| OMX_IndexConfigAudioVolume | Query / set the volume control. This currently controls the software
  volume that occurs prior to mixing in the platform audio output. | 
| OMX_IndexConfigAudioMute | Query / set the mute status of the audio output. | 
| OMX_IndexConfigBrcmAudioDestination | Query / set the audio platform-specific destination for audio output. | 
| OMX_IndexConfigAudioRenderingLatency | Query the current audio rendering delay in samples. | 
| OMX_IndexConfigLatencyTarget | Query / set the filter values used when tracking audio rendering latency
  by changing the clock speed. | 
| 101 | OMX_IndexParamPortDefinition | Supports connecting to a port on a clock component. | 
| OMX_IndexParamOtherPortFormat | Supports setting the port format to time format. | 
| OMX_IndexConfigPresentationOffset | Sets custom presentation offset, used to adjust the audio video sync
  offset. | 
|  | OMX_IndexConfigBrcmClockReferenceSource | Query / set whether (when connected to a clock component) this component 
  acts as a clock master (default behaviour) or as a clock slave scheduling 
  the presentation of audio packets based on the media time reference. | 
| OMX_IndexConfigBrcmGlobalAudioMute | Query / set the audio platform-specific mute status of the audio output. |
