@lovel,
Welcome, and thanks for joining us here in the Roku Community!
We'd love to be of assistance here and would like to learn more about this. Could you tell us if you can still hear the bouncing Roku sound during the initial setup? If not, do this: from Settings go to System>>System restart.
If this doesn't work, please get back here and we'll further look into it.
Thanks,
Rey
