Clicking / noise with unlock

[Breece]

Hey all,

just installed the latest weekly (9.5. 16) and am noticing something weird.. When I turn on the screen I hear a faint clicking noise coming from the top speaker. It is followed by white noise.
I can't be 100% sure but I don't think this happened with stock.. It seems like turning the screen on activates the speaker somehow.

Any ideas? Is that a bug I should report?

Thanks in advance!
