Debian sound stopped working

Until today, I had my home Debian system working perfectly with 3 soundcards.
1. Onboard (integrated) soundcard on my i865 mobo (not used - not imortant)
2. M-Audio Delta 44 (ICE1712 chipset) - primary sound device
3. Soundblaster Live! (basically unimportant)

This afternoon I installed some software (.debs) and then next I knew, my main (M-Audio) soundcard had stopped functioning. Here's the best I can do at piecing together the events...
I normally use gnome 2.8, but I was in KDE 3.3 for this...

I installed via Synaptic (like I have installed hundreds of other apps) a few programs:
ams - synthesizer
fluidsynth - synthesizer (this one also installed some libs, I think)
ardour - multitrack recorder
qsynth - GUI for fluidsynth
bristol - synthesizer

After installing these, I logged out of my user account and logged in as root (in gnome) to fire up JACK and try these toys. When I tried qsynth, it said it couldn't do MIDI because there was no sequencer device. So I did a
#modprobe snd-seq
and set up the connections to route my eKeys49 MIDI controller to qsynth
It wasn't working as it should (JACK was running and the signal was being accepted by qsynth) sooo......

I decided to check if sound was working at all by playing an mp3 through xmms (which has worked flawlessly for months). Well, no sound. Almost no sound...there is a trace signal that I can hear if I crank my hi-fi power amp way up. Fearing the worst, I shut down all apps and restarted. Now, as user or as root - in GNOME 2.8, KDE 3.3, or Enlightenment 16 I have just a faint trickle of sound.
I checked the wires, the mixer levels (gmix), everything is as it should be. My CD player audio is connected to my soundblaster card and the output from there is normal signal level. But still no sound from my M-Audio card (major bummer). So, I think something in the programs I installed broke something either with ALSA or my soundcard's driver.

Oh, more info. I use gstreamer to test my audio system in gnome and it does not report any problems. I use alsasink. It plays the test tone, but it is also just a trickle. So I am at a total loss.

Here's my output from lsmod:

Any help would be MUCH appreciated. I worked for weeks to get my soundsystem working well and this problem has really bummed me out.

Not pretending to know what your problem is but KISS wise, have you tried uninstalling the programs you installed to see if that fixes the break?

Thanks for the quick reply audibel! Haven't tried uninstalling yet. I will this weekend.
I have tried alsaconf with my M-Audio card and it didn't work (after upping the volumes in gmix). Then I ran alsaconf again and chose my Soundblaster card. It works fine. Unfortunately, I need my M-Audio card for multitrack audio recording, so I'm going to have to continue searching for a solution.

I'm currently having a similar problem. I have to run alsaconf each time I reboot to get sound working again. This was after upgrading my kernel (just upgrading the binary via apt-get) and after replacing discover1 with discover (and then going back again).

As it turns out, it was an issue with my stereo preamp. Nothing related to Linux or the computer. Before I figured this out, I ran alsaconf and, though it configured my M-Audio card just fine, it did not configure the Soundblaster card (though it still loads the module snd-emu10k1). Unfortunately, this card is not listed in /proc/asound/cards. So, my question has morphed. Now it's "How do I configure ALSA to load this other card as well?"

Epilogue from me too: I had to first run alsaconfig and get the sound working. Then I had to run 'dpkg-reconfigure alsa-base' and then, when prompted, told it to save its config file just this once. Sound was then working, and also worked fine upon reboot.
