Default Reversing broken updates

I would like to know how best to revert to an earlier version of
PulseAudio. The reason is that an update to PulseAudio broke my ability
to capture sound on my netbook.

I use aptitude for my package management needs and looking in its log I
saw the following (hopefully) useful version information:

Will install 14 packages, and remove 0 packages.
================================================== =============================
[UPGRADE] libpulse-browse0 1:0.9.14-0ubuntu20.2 -> 1:0.9.14-0ubuntu20.3

[UPGRADE] totem-mozilla 2.26.1-0ubuntu5 -> 2.26.1-0ubuntu5.1
[UPGRADE] totem-plugins 2.26.1-0ubuntu5 -> 2.26.1-0ubuntu5.1
================================================== =============================

I assume it is PulseAudio at fault rather than Totem. I am using an Asus
EeePC 1005HA, with Ubuntu 9.04, and up until this problem hit me, the
whole system had been working very well.

The question is, can I tell aptitude (or any other package manager) to
go back and reinstall those specific earlier versions of the PulseAudio
packages? If so, then please would some kind person explain how to do
it. If this is not possible then:

I have a full backup of my system from before the audio capture was
broken, but I have done a lot of work since and I would not wish to lose
it all by restoring the backup in its entirety. Restoring just those
files that relate to the pre-update PulseAudio would be better, but then
I do not know how to be sure I am restoring the correct files and
keeping the apt(itude) databases correctly synchronised.

Can anyone help me or point me in the right direction?

you can use synaptic package manager (in system > administration).
search for pulseaudio, then highlight the package. now, select package

Ok, I'll try that. Thanks.

But first, another backup... ;-)

D'Oh! I've just discovered that aptitude has the same feature. Somehow I
missed it, but once I knew it was possible in Synaptic, I tried harder
and found it. In aptitude you just select the package and press v which
then shows the available versions, cursor to the right one, and install
it in the normal way. Easy when you know how. I mention it here for
future reference.

Thanks again.

I suppose you mean the aptitude gui instead of the cli interface.* If no, would you please give the cli command to do that.* I would be* most interested if it could be done with the cli interface.* Thanks

Yes, I was refering to the interactive Curses interface.

thanks for the explanation. The gui is good and powerful but a little cumbersome to use. It's getting difficult to remember what your original issue was exactly. Did you get it resolved? If not, you may want to restate it for additional help. Good luck in your efforts but as said before
your probably ok until the next fsck error message comes up.

You can get the versions of a paclage that are available in your
enabled repositories with
apt-cache showpkg <packagename>

In the case of pulseaudio, there is only one Karmic version though.
