For the low latency configuration, AAudio should be used by the app in low-latency callback mode. For the streaming configuration, a Java AudioTrack should be used by the app. In both the low latency and streaming configurations, the HAL output sink should accept either AUDIO_FORMAT_PCM_24_BIT, AUDIO_FORMAT_PCM_24_BIT_PACKED, AUDIO_FORMAT_PCM_32_BIT or AUDIO_FORMAT_PCM_FLOAT for its target output format."
