dsp problem

Hi all,

I have a problem which is showing up through an error message on the opening screen of my KDE.

It is an arts message (Informational)

Error while initializing the sound server
device /dev/dsp can't be opened (No such Device)

Sound server will continue using the null o/p device.

my first stop was /dev/dsp of course.

Here i have found the following -


all of the above when opened with a text editor contain nothing at all. They all have the chardevice icon although /dev/dsp is slightly different because it has a shortcut icon or an arrow in the bottom left of the icon too. When I look at the message whilst poised on the /dev/dsp it shows me there is a link dsp->dsp0

This is as far as I have got really. I have messed about with the kde control panel part of the desktop but in the sounds config part I just get the same message about the initialization I am using the driver emu10k1-v0.20a which is definately the correct one because I have had it working on the first install with this.

Thanks for your help!

What soundcard do you use?
Did you enable sound card support for your card in the kernel?
Are you using ALSA ?
Try running sndconfig to configure your sound card.
Stop the arts server from running automatically from the control panel.
Check the /dev/dsp* devices.
Do an lspci to see what devices are recognized.
post an lsmod output so that we can see whether the sound card module is loaded or not.
char devices cant be read with a text editor.

kde sets the /dev/dsp to /dev/dsp0 when it cant initialize the arts server. Stop arts and after confirming that the sound card mnodules are loaded into the kernel, set the output plugin of XMMS to OSS driver and give /dev/dsp as custom device. Check whether you get sound.
Also do a [root!qqq /root]# cat /dev/random > /dev/dsp
and see whether you get sound on your speakers.

Thanks a lot for your post I have sorted it out now. It was the modules that had not been loaded properly.
