[Alsa-user] I can't use 'modprobe snd-via82xx'

[takashi <twa...@te...>]

Hi, how are you?
  I use Redhat9.
I installed ALSA driver for my 'via' on-board sound card.
  The installation seemed to be o.k at the beginning. However, as I 
tried to execute the commands like 'modprobe snd-via82xx', I get the 
error message saying that

/lib/modules/2.4.20-8/kernel/sound/pci/snd-via82xx.o: 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
/lib/modules/2.4.20-8/kernel/sound/pci/snd-via82xx.o: insmod 
/lib/modules/2.4.20-8/kernel/sound/pci/snd-via82xx.o failed
/lib/modules/2.4.20-8/kernel/sound/pci/snd-via82xx.o: insmod snd-via82xx 
failed

Now at the point, I used the command 'alsamixer'. Then I get the error 
message that

alsamixer: function snd_ctl_open failed for default: No such device

The funny thing is I can still use ALSA because whenever I use mplayer, 
and look at /proc/modules,  I can see those ALSA drivers there.
   Could anybody help me?
Lately, I have been trying to use a telephony software called "Speak 
Freely'. However, whenever I try to launch the program, I get the error 
message that

  Error opening PCM device plughw:0,0
                                            sfmike: unable to initialise 
audio.
 
        Unable to initialise audio.
                          sflaunch: New connection (return to exit)?

I thought this information might help to know why this whole thing is 
happenning.
Thank you, and have a good day.
