LinuxQuestions.org - RHEL4 sound problem

I am using RHEL4 and I am am completely unable to configure sound. my system has nothing like "/dev/dsp" or "/dev/sequencer".

Code:

[root@raj etc]# alsamixer 

alsamixer: function snd_ctl_open failed for default: No such file or directory

Code:

[root@raj etc]# uname -a

I installed latest alsa drivers from alsa web-site, they installed fine, I checked my card requires snd-hda-intel module but when I try to load the module I get this:

Code:

[root@raj etc]# /sbin/modprobe snd-hda-intel
