SKAA cmd APP
SKAA cmd lets you name each audio device (examples: “Kitchen speaker”, “Mike’s headphones”) and gives you individual volume and mute controls for each — all on one screen. You can also control them all at once with master volume and mute.
Adjust which audio channels are routed to each device (left, right, stereo or mono) — great for setting up stereo pairs of speakers.
