Couldn't open mixer device /dev/sound/mixer

laurentwahl · 05-14-2005, 05:46 PM

i've redhat9 with gnome and the kernel 2.4. I've newly installed oss and the installation worked fine. the test after the installation worked perfekt. but now everytime, when I start my computer, he says:

Quote:

and when I run volume control, he says

Quote:

Unable to open audio device '/dev/mixer'

Now I can't hear anything, because the volume is set to low

have you checked the permissions?

laurentwahl · 05-15-2005, 03:07 AM

I have checked the permissions of /dev/mixer

Quote:

lrwxrwxrwx 1 root root 11 May 14 23:07 mixer -> /dev/mixer0
crw------- 1 laurent root 14, 0 May 14 23:27 mixer0

this must be right, or not?

But I don't have a /dev/sound folder, and so I don't have the device /dev/sound/mixer.

even when i am logged in as root it doesn't work.
perhaps I have to reinstall a mixer. where can I download such a mixer and which mixer should I download for oss?

try:
chmod 777 /dev/mixer0
chown root /dev/mixer0
mkdir /dev/sound | ln -s /dev/mixer0 /dev/sound/mixer

I've now created /dev/sound/mixer and changed the permissions like muddlnx said but when I restart then my computer he rechanges the owner to laurent and the permissions to crw and I receive the same errors.
how can I disable that the system changes this?

I reinstalled oss and now it works. I don't know what I did wrong the last time.

Maybe the installer had messed up on the initial install. Maybe modules install, etc.
