pulseaudio-module-udev has been subsumed into the pulseaudio package
in Lucid. I've simply built it in the PPA for Karmic, so that's
expected.

The rtkit Conflicts I may need to readd just for the Karmic PPA
version. You should deinstall it.

Yes. You may need to wipe out ~/.pulse* after a session logout. This
is actually one of the reasons I'm using the PPA version -- to get
early testers going through the 9.10 -> 10.04 partial dist-upgrade of
PA.

Input -> Line out
Microphone -> (self-explanatory)

If you have both options, you actually have a selector at the mixer
level. I suspect you'll have to do similarly to the playback levels.

There is a corresponding alsa-utils alsactl init setting that was just
recently committed, but that will only land in Lucid. I can see about
backporting that to the Karmic PPA, but it'll have to wait due to
work. And it looks like it affects exactly what you mention next...

Only in the sense that Karmic's alsa-utils alsactl init doesn't
actually set it properly. But, the initscript does set it, so yes,
there is arguably a regression here. The real regression is that PA
seems to be doing things behind your back in a working session
(presuming you did the upgrade while logged into GNOME).

Are these symptoms reproducible across a reboot?

Yes, forcibly downgrade to Karmic's version, rm -rf ~/.pulse*

I will not be attending UDS-L.
