I use the Hardware Browser in X-Windows and it shows two unknown devices:

Creative SB16 PnP: Audio
Creative SB16 PnP: Game

But when I use the Sound Card Detection icon, it cannot detect anything.

How could I get this fixed?

Try opening a console, su to root, then try sndconfig and see if it finds your card.

After execution of /sbin/sndconfig

It says "can't not find plub and play or PCI sound card".

I manually choose SoundBlaster 16 and enter the IO/IRQ/DMA as indicated in my MS-Windows setting:

IO:220
IRQ:5
DMA:1
DMA:5
MPU IO:330

But I got the modprobe error as the following:

..../kernel/drivers/sound/sb.o: init_module: No such device
..../kernel/drivers/sound/sb.o: init_module: insmod
..../kernel/drivers/sound/sb.o: init_module: failed
..../kernel/drivers/sound/sb.o: init_module: insmod sound-slot-0 failed

What else can I do to fix this up?

Is it possible that these hardware setting is already occupied by other devices?

Disable PnP from within your BIOS. Is this a ISA or PCI card?

I think it's an ISA card.

And you've disabled Plug and Play from the BIOS?

When I turn on my computer, there's a line:

Initializing Plug and Play Cards...
Card-01 Creative SB16 PnP

In the BIOS I've already change the "Resource Controlled By" from Auto to Manual.

But the exactly same situation persists.

Isn't SoundBlaster card supposed to be mostly widely support?

Is it possible for me to look at what resources are used up by which system hardware devices?

You still haven't answered my question though. Did you disable PnP in your BIOS? Most ISA cards will not work in Linux if you have this enabled.

There's no such option in my BIOS to disable PnP.

There's a menu item "PnP/PCI Configuration" in the BIOS setup screen, it only contains two options:

1. Resource Controlled By [Auto/Manual]
2. Reset Configuration Data [Enable/Disable]
