> But honestly with both methods, we have a11y issues with shared machines

Sure, but it's much less with system-wide volume: all a blind user needs to remember is roughly how long the machine takes to start up. Then if they haven't heard the drumbeat, they can adjust the volume, and that volume will actually work for the screen reader.

No, it's just that primary sound input isn't yet specified in the way primary sound output is.
