4.8.5 Unicast Client Initiates Enable Operation (Page 48)

  Test Purpose:
  Verify that a Unicast Client IUT can initiate an Enable operation for an ASE
  with a Unicast Server that is either in the Audio Sink role or the Audio
  Source role.

  Pass verdict:
  The IUT successfully writes to the ASE Control Point characteristic with the
  opcode set to 0x03 (Enable) and the specified parameters.
