Question device /dev/dsp can't be opened (No such device)

I have been strugling to get my sound card working in Redhat 8. It is a Avance AC'97 for VIA.

I have installed the ALSA drivers and can see them in the lsmod:

snd-via82xx 11628 0 (unused)
snd-pcm 82144 0 [snd-via82xx]
snd-timer 15368 0 [snd-pcm]
snd-mpu401-uart 4716 0 [snd-via82xx]
snd-rawmidi 18336 0 [snd-mpu401-uart]
snd-seq-device 6144 0 [snd-rawmidi]
snd-ac97-codec 35940 0 [snd-via82xx]
snd 39820 0 [snd-via82xx snd-pcm snd-timer snd-mpu401-uart snd-rawmidi snd-seq-device snd-ac97-codec]
soundcore 6500 0 (autoclean) [snd]

I am not sure if I have the modules.conf entry right:

alias char-major-116 snd

When I login on KDE i get the message "device /dev/dsp can't be opened (No such device)"

Any Ideas would be appreciated.

It's possible that something (like arts) could be using your device but you can check if your device is still there with:

# ll /dev/dsp

If don't you can recreate it with:

# mknod /dev/dsp c 14 3

If the device exists, try to check who is using it with:

# ps aux | grep `fuser /dev/dsp`

Hope that helps...

1. /dev/dsp exists
2. fuser /dev/dsp returns null

Exists as what?

ls -al /dev/dsp ... is it a symlink to something (such as to /dev/sound/dsp , etc) that doesnt exist?

I would go ahead and delete it and recreate it. The previous post was correct in how.

I have SB Live! sound card and pinnacle PCTV tuner and also
get message " Device /dev/dsp can't be opened'.

when I type:

root@darkstar:/home/user# mknod /dev/dsp c 14 3
mknod: `/dev/dsp': File exists

root@darkstar:/home/user# ps aux | grep 'fuser /dev/dsp'
root 909 0.0 0.1 1672 604 pts/1 R+ 03:17 0:00 grep fuser /dev/dsp

user@darkstar:/dev$ ls -l dsp
lrwxrwxrwx 1 root root 4 2006-11-18 13:50 dsp -> dsp0

bash-3.00# ls -l dsp0
crwxrwxrwx 1 root audio 14, 3 2003-08-29 07:47 dsp0

I don't have sound.
