I am afraid the day may come when I can't get audio equipment with a mechanical volume control (without a layer of software in between). Even today, some laptops rely on software to mute their speakers when the headphone jack is connected.

I dread the scenario of being in a public place, like a library or about to give a talk, resuming my laptop from suspend, and loud music (or worse!) blaring out of the speakers, with all audio controls unresponsive as the system churns (or crashes!) under the load of resuming.
