I have Realteck ALC850 soundcard with AC97 drivers. I have no problems at all with sound. When installing Leopard I only have chosen AC97 drivers from the list. That's all.

I have the only problem so far. Every time I restart/start Leopard only English language remains in my Language Input Menu. I have to set again and again other two languages after restart to be able to type using them. And everything works ok until next restart/start of Leopard. I'm not sure if this problem was when I installed Leo, probably not, it has appeared later - I can't recall really. Anyone experienced this problem or knows where to search or how to solve this problem?

By the way, for sometime I couldn't solve the problems with finding the printer in Print and Fax Preferences (even it was identified in System Info) even after downloading latest HP sofware through Apple update. The problem was solved after I launched file "csregprinter" in System\Library\Printers\Libraries. Maybe this will help others who have similar problem.
