Plug & Play OS *is* disabled in the BIOS. The BIOS allows me to "hard set
IRQs" and IO ports for only a few devices, the serial and parallel ports as
far as I remember, not for the sound card anyway. But, hard set or not, the
IRQ and other hardware settings for the sound card drivers *are* the same in
Windows and Linux. I carefully checked that, and reported the values in my
original message.

So .... I don't think you just provided the key to a solution.

Thanks for your follow-up though!
