For anyone else who is also experiencing these noises and having trouble replicating it for your service depts., here you go.

This video includes all the best examples of the weird "tock" sound I have been able to capture thus far. I included some clips of a strange "whirr" sound I've also been hearing under some circumstances. Usually, the whirr sound occurs as I let off the gas, but only sometimes.

Hopefully, this video can help SoA and the Subaru service departments diagnose and figure out what is causing these noises. :)
So the chirping sound that you hear when going from reverse to drive happens for me as well and you can hear it very pronanced outside the car and the sound is coming from somewhere in the driveline possibly the CVT. It only happens for me when the car is cold and in 1500 rpm high idle mode. If the car is already up to tempture I never here the chirp.
