Hello!

I'm a newbie, actually I'm using Debian Woody 3.0r2 and it run very well, but yesterday I changed my Desktop Manager (KDE) to Gnome. Today I changed again to KDE and the soundcard has a problem, this is the window message that appear:
Sound Server Informational Message

Error while initializing the sound driver:
device /dev/dsp can't be opened (Permission denied)

The sound server will continue, using the null output device.

That's all, and I can't hear anything. Please, I need your help!
Thanks.

PD. I have a Cmedia 8738 soundcard

Did the sound work before the Gnome switch? Did it work during your time in Gnome?

What are the actual permissions of /dev/dsp? Maybe something in Gnome's setup resulted in changing permissions? Or, maybe you're using a different user that isn't in an audio group you may have designated?

Yes, my soundcard was working, I don't remember if I play any sound in Gnome, but before, yes, it work.
Well, you say that maybe I'm using a different user and you are right, because I did the switching desktop when I was root, but finally, when I start KDE I use a normal user because when I try to start KDE a message appears saying me that root is not allowed to start any desktop manager.

crw-rw---- 1 root audio 14, 3 dsp

that's the permission of file.

Run the following commands to change the permissions of /dev/dsp and /dev/mixer
That should eliminate any permission errors. Good luck with it -- J.W.
