You have more than one audio device:
00:04.0 Multimedia audio controller: nVidia Corporation CK804 AC'97 Audio
Controller (rev a2)
01:07.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio
Decoder (rev 05)
01:07.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and Audio
Decoder [MPEG Port] (rev 05)
Which one would you like to use? Drivers for CK804 AC'97 looks loaded fine. Can
you attach a screenshot of the first page of system-config-soundcard? (with the

I think the other device is just sound and video input from the TV card, which
I'd tell you more, but hwbrowser seems to be broken. I'll file a bug on that next.
The sound device is on the MB. I have no separate sound "card" in the system.
Is this bug related to BZ#283371 by any chance?
I don't think so.
But the screenshot looks sane, does the sound work?
If not, can you please run the latest system-config-soundcard, switch to the
"System" page and try to "Reset configuration files"?
There seems to be an awful lot of churn in the sound systems, but currently
system-config-soundcard is working for me. It finds the nvidia sound device and
plays the test sound. Its just a shame that nothing else seems to recognize
the device that was found. The Volume control on the panel says it can't find
any elements or devices to control. Tvtime, which used to have sound even when
system-config-soundcard didn't work, now can't access /dev/video because
something else broke the permissions! If I chmod 666 /dev/video, the video
works but now no sound. Secondlife binaries, no sound.
Basically the sound system is a mess. Fixing the entire sound system should be
a blocker for FC8!
Oh yes, selecting "System" tab and "Reset configuration files" produces:
Unable to remove kernel modules. You need to reboot your box
for the changes to take effect.
"Reload audio drivers" does the same thing.

It's not a bug. Your audio is used by some other application so the modules
can't be removed from kernel.
Okay, closing as fixed for now.
