For all you people searcing for more information on getting the C4237B soundchip working under Ubuntu, here are the links to my previous posts on the subject:
Some other people out there in Internet land have reported the steps detailed in those posts as working for them. Some have reported that they don’t work. *shrug* My best guess as to why is I think the chip can be configured with a DOS/Windows utility to use different IRQs and what not. Or it could be some sort of difference in the kernel(s) people are using. Or something else entirely. I really don’t know for sure. Lastly I should note that when I last updated the kernel on my laptop to tot 2.6.12-10; the sound stopped working.
