audioGroupId
Specify the audio rendition group for this audio rendition. Specify up to one value for each audio output in your output group. This value appears in your HLS parent manifest in the EXT-X-MEDIA tag of TYPE=AUDIO, as the value for the GROUP-ID attribute. For example, if you specify "audio_aac_1" for Audio group ID, it appears in your manifest like this: #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac_1".
