Sound Quit Working

[killthesand]

I'm running Fedora Core 6, 64 bit, currently kernel 2.6.19-1.2895.fc6. I have a Creative Sound Blaster Audigy 4 Professional.
I installed a few days ago, everything was working perfectly until this afternoon my sound quit working for no obvious reason. The first thing I did was System - Administration - Soundcard Detection. It sees my sound card and my motherboard's on board sound. The Creative Labs SB Audigy is the default card. The sound module is snd-emu10k1. So far everything seems good. Down below, the PCM device is blank. When the firstboot wizard ran, there were about seven different choices here, now there are none. I'm pretty sure that the problem is here somewhere. When I play the sound test, it immediately asks me if I heard the sound, there is no time for a sound to actually play. If I look into Alsamixer or kmix, there is nothing there, no sliders or anything just blank. Trying some things I found online, I did a
chmod 777 /dev/audio* /dev/dsp* /dev/mixer*
that didn't appear to do anything. I tried alsaconf as root, command not found. When I try to play a file I get some of the following messages

Cannot open the audio device. Another application may be using it.

Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (No such file or directory)
The sound server will continue, using the null output device.

Could not open/initialize audio device -> no sound.

I have tried to do a modprobe snd-emu10k1, that seemed to have no effect, the module appears to be loaded alright. What is responsible for loading the possible default PCM devices? Thank you for any help you can provide, I've exhausted evrything I can think of to restore my sound. It's very annoying not to have it.

Wanted to make sure the emu10k1 is the first snd device 0.
How about pulling the card and reeating in the same slot or move to a differnet pci slot.
If you do ' alsamixer -c1 ' it should show sound levels for the intel device. ' alsamixer -c0 ' would be the first.
Not sure what else to do. Modules are loaded, modprobe.conf looks good, just out of ideas.

Check about 2.6.18 - 2.6.19 changes here .
One of the things done for 2.6.19 was to remove sound drivers.

[EDIT: check here for more specific info about the sound drivers]

After several months I've finally found the solution to my problem. If someone else has the same problem, here is the solution, and it's simple! I'd been using my motherboard's on board sound just fine, but my audigy still didn't show any PCM devices. While I was trying to set up my TV tuner, I ran into an issue where the tuner didn't have any audio output; it sends audio in through the PCI slot. I needed to activate it as an audio device. I found that the TV tuner was using /dev/snd0, the active soundcard was /dev/snd1, and the inactive soundcard was /dev/snd2. As I was tinkering in the Soundcard Detection I went to the second tab and changed the device order. Moments later I heard sound from my speakers. I wasn't expecting that. All I needed to do to fix the problem was to set the tv tuner to device 0, the audigy to device 1, and the motherboard sound to device 2. If I want to switch to the motherboard sound then I just have to switch it to device 1. So if you are having trouble with your sound and all else is failing, try changing your device order and see what happens.
