If I boot up and use a F13 kernel, everything is fine. If I boot with
the F14 kernel, no sound.
It's possible there is a bug in the alsa interface in the F14 version
of the kernel. Changes are being committed all the time, and maybe one
of them had a regression.
Running the alsamixer shows as if sound is there (the levels jump
around), but no sound comes out the speakers. I have checked the alsa

My alsa setup is at

Try running aplay -l, look to see how many sound devices the OS thinks
you have. Your symptoms sound like you aren't playing sound where you
think you are. If it turns out to be the case that there is more than
one sound device, you can fix this by putting something
in /etc/modprobe.d or using pavucontrol to assign the sound devices in
pulseaudio. Sometimes modems and video cards have components that are
interpreted as sound devices, throwing off the placement of sound
