+# Ok, we probably need a little explanation here for what the two lines above
+# are good for.
+#
+# The story goes like this: when ALSA registers a new sound card it emits a
+# series of 'add' events to userspace, for the main card device and for all the
+# child device nodes that belong to it. udev relays those to applications,
+# however only maintains the order between father and child, but not between
+# the siblings. The control device node creation can be used as synchronization
+# point. All other devices that belong to a card are created in the kernel
+# before it. However unfortunately due to the fact that siblings are forwarded
+# out of order by udev this fact is lost to applications.
+#
+# OTOH before an application can open a device it needs to make sure that all
+# its device nodes are completely created and set up.
+#
+# As a workaround for this issue we have added the udev rule above which will
+# generate a 'change' event on the main card device from the 'add' event of the
+# card's control device. Due to the ordering semantics of udev this event will
+# only be relayed after all child devices have finished processing properly.
+# When an application needs to listen for appearing devices it can hence look
+# for 'change' events only, and ignore the actual 'add' events.
+#
+# When the application is initialized at the same time as a device is plugged
+# in it may need to figure out if the 'change' event has already been triggered
+# or not for a card. To find that out we store the flag environment variable
+# SOUND_INITIALIZED on the device which simply tells us if the card 'change'
+# event has already been processed.
