A CIG has one CIS per direction of every member of a coordinated set, so four of them are needed for a stereo stream to a set of two. Take the maximum the command allows, which the handles of a CIG have room for: they start at CIS_HANDLE and the ones of a BIG only start at BIS_HANDLE, 256 handles later.
