commit f480fb38a7ca0da07801e90f907fb98228261bf6

sink-input, source-output: Assign to reference_ratio from a single place
This makes it easy to log a message every time the reference ratio
changes. I also need to add a hook for reference ratio changes, but
that need will go away if the stream relative volume controls will be
created by the core in the future.
