I believe pulse audio is present on your system.
I assume, if you do, ps wx | grep [p]ulseaudio
you will see something like
rsewill@rsewill:~ <3:6> $ ps wx | grep [p]ulseaudio
2463 ? S<sl 8:42 /usr/bin/pulseaudio --start
Have you used pulse audio before?
Try running kmix with KMIX_PULSEAUDIO_DISABLE=1 as in the following script.
rsewill@rsewill:~ <3:1> $ more bin/kmix-alsa
export KMIX_PULSEAUDIO_DISABLE=1 && kmix
rsewill@rsewill:~ <3:2> $ ls -l bin/kmix-alsa
-rwx------. 1 rsewill rsewill 54 Oct 20 00:27 bin/kmix-alsa

The above script may get kmix to show the alsa controls.

There is a pulse audio mixer control, pavucontrol, for the PulseAudio sound
rpm -q -i pavucontrol
You may need to install it, yum install pavucontrol

You say it did not recognize all your sound devices and multimedia formats?
You will need to be more specific...what sound devices are recognized?
What sound devices are not recognized?
Do you mean you have multiple sound devices such as an internal sound card,
a USB sound device, what?
Do you mean you plugged something into the sound jack and the internal sound
card isn't behaving properly, such as not doing surround sound or something?
If this is a problem, this opens up, for me, a can of worms.
It's possible you need to do something like create a file in /etc/modprobe.d
that passes various options to snd-hda-intel
Before going down this path, we need to know if this is, indeed, your problem.
I always get lost and confused going down this path and welcome others help.
What multimedia formats are recognized?
What multimedia formats are not recognized?
The comments, regarding pulse audio, are related to sound devices.
When you say it doesn't recognize multimedia formats, do you mean formats
like mp3? Fedora doesn't, by default, provide the software for mp3 because
mp3 is a proprietary format. If you are using audacious, you might need
rpm -q -i audacious-plugins-freeworld-mp3
found in the repository rpmfusion-nonfree
If you are using something else that uses gstreamer,
you might need gstreamer-plugins-bad or gstreamer-plugins-ugly or I don't know
A disclaimer...I am interested in sound discussions because I always have
problems with my own sound configuration. Usually, when I try to answer
these questions, some kind soul corrects me and both I and the OP learn.
