    tunnel-sink-new: Fix stale audio on resume
    
    I noticed that when resuming the tunnel sink, there was a small amount
    of previously played audio before the new audio started to play.
    Normally that probably wouldn't be noticeable, because there would be
    a few seconds of silence played before suspending the sink due to
    inactivity, so the unwanted old audio would be just silence, but in my
    configuration sinks are suspended immediately when there's nothing
    playing to them, so the glitch becomes audible.
