The firmware that came with my console had an issue where there was high pitch noise whenever there was a change on the main menu. FunKey S Project moved quickly and fixed it in the release 2.0.1. Then 10 days after they issued another FW upgrade.
It is refreshing that the company does this so often after a successful Kickstarter campaign.
