LinuxQuestions.org - Problem starting sound card on Acer Travelmate

I am completely new to Linux and have installed Mandrake 9.1 - everything is working (even got the wireless network with WEP to work!), except for the sound card.

I've been looking on the forums to try to find a solution but can't find anything. From other posts the following seems important to you out there, in order to help, so here goes:

Code:

# modprobe trident

/lib/modules/2.4.21-0.13mdk/kernel/drivers/sound/trident.o.gz: init_module: 

No such device

Hint: insmod errors can be caused by incorrect module

 parameters, including invalid IO or IRQ parameters.

      You may find more information in syslog or the output from dmesg

modprobe: insmod /lib/modules/2.4.21-0.13mdk/kernel/drivers/sound/trident.o.gz

 failed

modprobe: insmod trident failed

and

Code:

# modinfo trident

As I mentioned, this is all completely new to me, so any instruction would be useful! Cheers. :)
