In UCM basic functions, we only assign intended roles from modifier to sink/source, but we don't have a chance to set the ucm modifiers. Here we amend the functions so that when roled stream starts or stops, we have the following results: 1. stream will be routed to sink/source specified in modifier by module-intended-roles 2. After that, modifier will be enabled or disabled. 3. when multiple streams with matched roles of modifier start, only the first one will enable the modifier, and when they end, the last one will disable the modifier.
