nV News Forums - Audio not working with Fedora Core 3

I am running Fedora Core 3 with a 2.6.12-1.1381_FC3 kernel and a Gnome desktop. My setup is pretty much the standard way that Fedora Core 3 gets installed. My audio does not work properly even though the nvsound module appears to load correctly. If I perform "cat /usr/share/freeciv/stdsounds/gong10.wav >/dev/dsp", I get appropriate sound in the speakers. However, the following features do not work.

(1) I cannot play sounds through applications like RealPlayer, kaboodle, etc.

(2) When I select Sound & Video->Volume Control from the desktop menu, I get an error window with the following message. "Sorry, no mixer elements and/or devices found."

(3) I have a volume control icon on my taskbar. When I left-click it, it displays a vertical slider bar for the volume. I can drag the volume up on the bar, but it immediately falls back down to zero volume even before I release the slider. When I right-click on the icon, I can select "Preferences". Doing so opens a window where I should be able to select an audio channel, but the "Audio Channels" list is empty.

(4) When I select System Settings->Soundcard detection from the desktop menu, a window titled "Audio devices" opens with the following information:

The following audio device was detected.
Vendor: nVidia
Model: Corporation: Unknown device 026b
Module: nvsound

There is also a "Play test sound" button. When it is pressed, no sound occurs, and a window pops up asking if a sound was heard. When "No" is pressed, a window appears that says "Automatic detection of sound card did not work. Audio will not be available on the system. Please click OK to continue."

(5) I have run nvmixer and ensured that all volumes are high and all mute selections are disabled (no muting).

BTW, I have no problems with the network driver nvnet.

Here is the troubleshooting that I know to do and the results.

Here is the output of the lsmod command showing the nvsound module is loaded and associated with the soundcore module (whatever that is).

I don't know exactly what I am reading, but the "Nvsound: Audio getting removed" entry catches my eye.

Does anyone know what the problem may be? Failing that, if a few people that have gotten their nvsound module to work could post the results of running "lsmod" and "dmesg", the differences between a working setup and my non-working setup may be useful. Well, maybe the parts of "dmesg" that have to do with NVIDIA or nvsound, since "dmesg" output can be pretty long. Thanks.
