BAP/BSRC/SCC/BV-35-C [Establishes Broadcast] (page 175):

    Test Purpose:
    Verify that a Broadcast Source IUT can establish a broadcast
    Audio Stream.

    Pass verdict:
    The IUT sends AUX_SYNC_IND PDUs with an Extended Header
    containing BIGInfo in the ACAD field.

    The IUT sends BIS Data PDUs over the broadcast Audio
    Stream.
