Audio issues: What do I delete to make a clean start in alsa?

Background: I'm having major problems with audio - briefly had my headset mic working with Skype, then it stopped. Then audio out stopped too - I have no sound from the speakers as well as from the headset.

I've decided to go back and start from scratch. I uninstalled phonon (and the couple of KDE apps I had installed, that depended on phonon). And I've uninstalled pulseaudio (did that weeks ago as part of getting audio working).

The question: Now I want to make a clean start in alsa, as my first step in getting audio working (whether or not I install pulseaudio later).

I guess I should uninstall and reinstall - but which config files should I delete [backing up of course]? Anything starting with alsa in /etc/modprobe.d + .asoundrc... anything else?

Distro: CrunchBang Statler (basically a respin of Debian Squeeze)
Laptop: ASUS A42-F-VX085D
Audio: Azalia compliant audio chip, with 3D effect & full duplex with Altec Lansing speakers, SRS Premium Sound.
Headset input: a single spot for a plug.
Headsets: I have my regular headset with a 2-to-1 plug adaptor, and a USB headset.

Apt-get can remove the configuration files for you. apt-get purge <packagename>.
From the apt-get man page:
purge is identical to remove except that packages are removed and purged (any
configuration files are deleted too).
Unfortunately, that doesn't help you identify the configuration files to backup.

To get those file names, you can simulate package removal and pipe the output to a text file that you can peruse for filenames.

apt-get --simulate purge <packagename> | tee rempackage.txt (or whatever you want to name the text file)

From the apt-get man page:
-s, --simulate, --just-print, --dry-run, --recon, --no-act
No action; perform a simulation of events that would occur but do not actually
change the system.
