I have this problem with my laptop.
I use a compaq armada 1750 with slack9.
When I try to check the sound using kde control center I get no
sound. Also, the output of lspci does not contain listing of a multimedia device:


00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03)

I know this could be an acpi problem - but I tought that was fully integrated into slack9.

Any idea?

Linux on laptops covered it, doesn't look like an ACPI issue as much as a Compaq is flaky issue.
