I installed Macromedia, mplayer, vlc. I tried to watch

System -> Preferences -> Personal -> volume control
I now do not hear sound when I select
System -> Administration -> Soundcard detection.
What could explain the soundcard not being detected?
Should I reinstall Fedora 7?
I sent an email out on Monday, 20th Aug to which noone
has responded. Are people tired of helping people get
sound working? Is the subject of no interest?
If anyone can give advice or feedback, I would appreciate
it. Can someone point me to documentation?
Thank you for your attention and consideration,

See if your sound card has been detected.
aplay some.wav this will use the default device
aplay -D plughw:0,0 some.wav uses a different plugin than default
You can also look at aplay -lLv to see the info alsa has about your card
and how it has configured it.
There is lots of information in /proc/asound as well.
By default alsa starts with sound muted, so use either the alsa mixer gui
or alsamixer in a terminal to adjust at least the master sound level.
If you have more than one soundcard, it is possible that they were
assigned in a different order than you expect. This requires explicit
assignment it /etc/modprobe.conf. Lately, I've noticed this occurring
by default.
Some applications need to be configured to use the card.
And yes, this question has been asked and answered many times on the
list. The answer has to be out there somewhere on the web, for sure on
either the alsa-user list or this list at gmane.org.
I'm sure you find the subject of interest. :-)
I've had pretty good luck with sound, the basic functions have just
worked. If you are using an obscure chip, or a troublesome chip it can
be problematic. And because every sound card is different, only someone
familiar with your card can really go beyond the basic stuff above. For
those, the alsa lists are probably the best bet. They can also tell you
if it is even supported.
