Lost Sound with Upgrade to 9.10

[robfleet at ix.netcom.com]

Greetings all,

Has anyone else had problems with sound (meaning NO sound) after upgrading from Ubuntu 9.04 to 9.10?  I thought maybe I had a sound card problem but I have installed other distros (this is on a non-production machine) on this computer and have no problem with sound whatsoever so it seems to be a 9.10 problem.  

If anyone knows of a fix, I'd love to hear about it.

Thanks in advance.

Rob
