Both of my Ooma Hub AC adapters (with date stamp of "09JUN") buzz...enough so to bug me in a quiet bedroom. Has anyone else noticed buzzing from their Hub AC adapter (even if you put your ear right to it)?
And are all of the Ooma Hub AC adapters the "old style" large/heavy kind? I would've preferred the lightweight/high efficiency "switching" power adapters that have become prevalent with equipment of this kind.
