The Audio ES Channel Buffer can contain any of the following audio
streams:
1. Linear PCM audio
2. MPEG-1 audio
3. MPEG-2 audio

ES Channel Buffer.
The Preparser adds a sync code and a data length field to the input
Linear PCM packet header to provide the on-chip audio decoder with
better error recovery features.
