not surprising this is one of the three most aggravating things about 
the *nix universe I find. Something works out great and you get it all 
playing nice together and then along comes an update and the printer 
quits working or the sound quits or the flash player plugins quit 
working and you are back to square one again troubleshooting for a fix 
to one or all of these items every time an update comes out.

sad but true and it seems to happen with all flavors of *nix mint, 
ubuntu studio , ubuntu desktop K and X. They all seem to be affected by 
the widespread malady.
