It would be good to know whether this upgrade included the kernel. Check
/var/log/dpkg.log* (or /var/log/aptitude* if you use aptitude).

Which command or media player did you use to check the sound? I would
start with something elementary like "speaker-test -t sine" and watch
for error messages.

Which sound devices do you have? Run
find /dev/ -group audio | grep -v '/.static/'
Check if this output remains unchanged after you start X.
Maybe some background process is blocking access to the sound devices.
You can test this with
lsof $(find /dev/ -group audio)
