Audio Selector puts every audio device on your Mac one click away in the menu bar - outputs and inputs alike - and shows the current device and format right there. It also changes bit depth and sample rate (up to 32-bit/768kHz) without opening Audio MIDI Setup, and a free iPhone app turns your phone into a remote for device, volume and format. Software volume for DACs with no volume control. Free to use; Pro is a one-time upgrade with no subscription.
