3.2.5.1.5 Sending a Sound Formats PDU

The structure and fields of the Sound Formats PDU are specified in section 2.2.2.2.

The client MUST respond to the Sound Formats PDU sent by the server by replying with its own Sound Formats PDU. The list of audio formats that the client sends back to the server MUST be a subset of the list sent by the server. Formats that are not in the server's list MUST NOT be included in the client's audio format list.

The list sent by the client establishes the allowed audio formats for the current protocol session. These formats MUST be referenced by the NewFormat field of the Format Change PDUs and the initialFormat field of the Open PDU. A value of I refers to the Ith format of this list and means that audio data MUST be encoded in the Ith format in the list.
