Yeah, putting logically equivalent regexps in multiple places sounds
like a bad idea.

I guess what I was trying to get at was that maybe mixer_applet's
logical mapping (which this argument presupposes is "correct", since
that seemed to be what the OP was saying) could be extracted into a
library which both mixer_applet and a command line program/init script
could both use. Of course, this would take a lot more work and
coordination with upstreams.

But it's no big deal, of course. It seemed like the proposal was going
to cause a regression for folks like me that have had sound levels
working fine across boots on a daily basis while fixing a sound level
problem that some face when upgrading. 

It looks like it won't have that big an affect on me, so I'm no longer
worried.

Thanks for taking the time to explain the technical details.
