Since F10 ALSA card indexes are not stable anymore to allow flexible
hotplugging setups. 

You don't need stable indexes. Simply use the card names instead. You
can find them in /proc/asound/cards. i.e. use "front:AudioPCI" instead
of "front:6" as device strings. That way you don''t need to configure
anything and always have stable device strings.
