Noise after shifting Outback?

Anyone else noticing a somewhat regular sort of light tapping noise from Subaru CVT Outback, when slowing to stop or starting out?

Some days it’s noticeable only for about a second after the clunk from shifting, often you can hear it a bit longer.

You can hear it best at about 1 min, and last 40 seconds of this short trip audio-clip.

Stumped? The noise has been somewhat rarer (maybe the warmer weather?) and the dealer says it’s mechanically-sound and not warrantied issue.

Video is not linking for me, Could be s many things, if you or a mechanic can isolate the source that is the best start, could be a tensioner, bearing, valve etc.

Well I haven’t heard the noise in maybe a year so I doubt I can isolate the source.
