Hello there,
not sure it is pulseaudio to blame yet (and again), maybe simply an
Alsa bug or incompatibility. I've recently installed Fedora 10 on a
brand new Dell Latitude E6500 laptop.
Few hours after the system has booted (an unpredictable amount of time)
sounds are simply not playing anymore - tried w/ apps, aplay, mplayer.
Did somebody experience the same? Or any clue where to investigate or
find a fix?
I'm running GNOME and default sound settings (pulseaudio, alsa), here
are some excerpts of `lspci -vvv` concerning the audio system:

And here is the output of a `grep -iE

several reboots across last 4 days, mostly to restore sound:
