+		 * one is actually plugged in, and some application may ask the user what was plugged
+		 * in. Such applications should get a list of all card ports and compare their

+		 * input from the user to determine which device was plugged in. The application should
+		 * then activate the user-chosen port.
+		 *
+		 * May be NULL, in which case the port is not part of any availability group (which is
+		 * the same as having a group with only one member).
+		 *
+		 * The group identifier must be treated as an opaque identifier. The string may look
+		 * like an ALSA control name, but applications must not assume any such relationship.
+		 * The group naming scheme can change without a warning.
