Hmm, it would be nifty if we could get the alsa card name (i.e. the
one shown in [] in /proc/pcm/cards) as an attribute file in
/sys/class/sound/cardX/name. Even more useful would be if this
property would be writable so that the cards may be renamed during

This could be very useful to establish stable card names via udev
rules, similar to what is already done to network interface names
("eth0", ...).

Would such a change be acceptable?
