Controllers can add custom argument SEQUENCE=<number> in browse commands to associate command and response. This is
possible because the 'message' field in the response packet includes all the arguments sent in the command. Please let us know if
you need additional custom argument other than 'SEQUENCE'. This is to avoid accidentally using HEOS command arguments for
special purpose.
Maximum number of simultaneous socket connections supported by HEOS speaker is 32.
