Sorry for a late reply, but I didn't notice the last point that you made
until now. Why should I sync analog-output's Desktop Speaker with
analog-output-speaker, as opposed to removing Desktop Speaker from
analog-output? If the Desktop Speaker element exists, then the
analog-output-desktop-speaker port will be created, and since that's
more specific than analog-output, analog-output should be suppressed.
Therefore, there's no reason for analog-output to care about Desktop
Speaker.
