Just to mention that since my last -current upgrade (21/03), my laptop
(an HP NX6310) displays different mixerctl table, which is much more
understandable than before - here is the sdiff output:

I browsed but couldn't find quickly when the change was made; thanks
anyway to whoever did it; otherwise it works just fine, including
through the speakers.

There are a few niggles - I can't figure out how to change the volume
within moc - it apparently responds to the ,. command, but the volume
stays the same, whereas amarok and vlc seems to be able to do it.
