A macOS menu bar app to keep your external speakers awake. Prevents power-saving switch-offs by playing an inaudible, low-frequency tone at regular intervals until the sleep timer runs out.
Update 11/11/24: New option to disable the sleep timer altogether, improved main icon/graphic and a fix for some weird scrolling that was happening in the menus.
I can't seem to get the automatic updates working without a developer license so you'll have to download the .zip below and manually replace the app I'm afraid!
