Where did my sound go?

[Jeffrey Ross <jeff bubble org>]

first this is an x86_64 machine running FC6.

I just updated the system with the latest updates with yum, two items I 
noticed that maybe of interest that were updated are ALSA and the 
Kernel.  Ever since these packages were updated I have lost the sound.

However... If I go to the sound card detection it play fine, run vlc and 
the machine is silent.  The web browser is silent and so is the mail 
client's (thunderbird) new mail notification.

The sound card in the machine is 06:02.0 Multimedia audio controller: 
Ensoniq 5880 AudioPCI (rev 02) per lspci and the sound card detection 
program says its module "snd-ens1371"

Suggestions?

TIA, Jeff
