Clicking noise from the back wheel

Hello everyone, I'm new here and I would appreciate to get your help.

I bought a new bike three months ago - Trek 4300 2014.
Two days ago I noticed a noise coming from the back wheel while pedaling forward, even in static mode while I move the bike forward I hear the noise coming from the area of the back wheel. I'm pretty sure that noise did not appear in th past, but I can't understand what is the source of this noise.

I uploaded a video:


I would appreciate hearing your opinions!
Thanks.

Sounds normal to me. The clicking is from the pawl mechanism which lets the bike coast while the cogs are stationary.

Two different sounds. The normal clicking of the ratchet mechanism inside the freewheel, when coasting. (note the linked image is for explanation, not a true representation of a hub's ratchet).

Then there's the chain on sprocket noise when pedaling. That's maybe a bit louder than normal. Could simply be due to changes or wearing of of lubricant, or that the derailleur is out of trim, and feeding the chain slight to one side of the center of the teeth. Trim adjustments are commonly needed after a month or two on new bikes, so you might let the dealer check it out next time you're there.

Otherwise, it's all good.
