I could use your guidance on a few topics:

Our infamous mixer init script suffers from a few flaws:

1) Mic input is muted on boot - this is not terrible IMO but I got it 
from the OEM folks who like things to work out of the box. I could 
probably fix this to just mute with the "nocap" option, without much 
work. That's the easy one.

2) Asynchronous problem - as Lennart Poettering pointed out [1] this 
script is executed asynchronously so it is not guaranteed to have 
finished when PulseAudio discovers the card. PulseAudio might take these 
mixer changes as changes by the user, and preserve them. His version is 
to execute a mixer restore script both on udev rule and on the file 
system showing up (?), since we don't know which one will happen first [2].

3) Upstream has started their own solution with the stuff in 
/usr/share/alsa/init and so our solution is in conflict and we don't use 
upstream's version.

Btw, how do I coordinate this with Debian? We inherit this script from 
there, so this concerns them as well.

While I have your attention, two additional questions:

* 1.0.24 is out and we plan to take it for Natty. I don't mind helping 
out, but again I'm a little unsure of how to coordinate with Debian - 
seems we sync/merge this from Debian and it would be stupid to double 
the effort?

* My pulse-mixer patch hasn't received much attention from upstream yet, 
although posted more than a week ago. Should I be bold and upload it to 
Natty?
