# 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.
