+Profile is a card-level setting, not a per-device one — pavucontrol puts it
+in its own "Configuration" tab for the same reason: a single card can back
+multiple sinks/sources at once, and switching its profile can make some of
+them appear or disappear entirely (e.g. "Analog Stereo Duplex" exposes both
+an output and an input from the same card; "Analog Stereo Output" drops the
+input side; "Off" drops both; "Pro Audio" breaks the card into raw individual
+ports instead of one grouped stereo pair). Output/Input Devices used to carry
+their own copy of this dropdown per-device, which was confusing when one
+card backed a device in both tabs — this replaces that."""
