Well your soundcard is detected, and all the relevant modules are loaded.
As the sounds were working before you rebooted, it may be that something in
the mixer may be muted.
Open alsamixer as user in Gnomes terminal. that should display just one slider
if pulseaudio is running.
Now close alsamixer using the "esc" key, and start alsamixer again using the
following command, which will show all the alsamixer settings.
alsamixer -D hw:0
You may find that some sliders are set to zero, or muted (the "M" key toggles
the mute/unmute). the main sliders of interest are "Master", "PCM", and
"Front", and also the "CD" one if your testing the sounds out using an audio
