lockdevice v1.6 ticking noise?

[itony]

This is really strange: When I push the sleep button on the top to turn of the screen and the lock turns on, every 10 seconds or so theres this very low tick noise kind of like a softer version of the noise made if you have the hardware buttons make a soft tap noise option on. The thing is though I let the screen turn off and lock by itself and it does the same thing.

So I turn of that sound option under sounds and notifcations and it stops. I don't mind doing this to solve the problem but I would rather find a solution then an alternative...anybody?

p.s. sorry if this is in the wrong area. Please direct me to where I should ask...(possibly xda i guess?)
