I think I got it. I don't know what I truly did, but it works now. In Sound System in Control Center under the hardware tab I selected a different MIDI device and somehow the testsound worked, and so does everything else now. Strangely, I could of swore that I did that before. Perhaps its was a combo of things.

Thanks all.

Glad it's working, but I can't explain that either. Maybe it's something else you did, but changing the MIDI settings forced it to restart the sound server and activate your changes.

Still, let's not complain.

Fedora 8 does matter: you will find that /sbin/lspci works. The error says nothing more than that bash cannot find the command, i.e., it is not in its default path.

I have been using Fedora 8 without any problem on the sound system for a month more or less.

Some days ago I changed somethings on KDE and since then, I'm getting the same results you are describing.
I test successfully my sound card using KDE-->system-->soundcard detection but it fails with KDE Control Center. Moreover, it fails as soon as I connect my user.

Well, I'm not able to explain any reason but (yum)erasing some packages, everything work again.
These are the packages I have erased:
I hope it will help to avoid the problem ... meanwhile
