Description of problem:
When installing FC4t1 on a brand new computer, I could not hear any sound. Upgrading to the latest development kernel did not help.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
3.Play the test sound
Actual Results: Nothing
Expected Results: A sound from the speakers.
When booting, I got the error message "Disabling IRQ #10". This prompted me to try with "acpi=off" on the command line. And that did help, I now do get sound. So I have a workaround, but I guess I'm not supposed to have to do that.

Mass update of -test bugs to update version to fc4.

I can not do a clean reinstall of the machine. But I upgraded to the recently
released kernel-2.6.12-1.1387_FC4. With this kernel, sound works even without
any acpi flags on the kernel command line.
Seems to be solved.
