no sound after yum update of working FC16

[dave perry]

This evening I did a "sudo yum update"  which included a new kernel and 
kernel headers.  So I reinstalled the Nvidia proprietary driver 
(290.10), rebooted and now I have no sound.

/var/log/yum.log shows the following record of this evening's update:

I tried booting the prior kernel  (3.2.6-3) and now I get no sound with 
that kernel.

After rebooting kernel-3.2.7-1.fc16.x86_64
I launched FlightGear from a command line and get permission errors

This system has been working great since a fresh FC16 install Feb. 16.

Does any of the above point to what was broken by the yum update?

Thanks in advance,
