sound device permission problem as user
 

I have slackware 9.1 installed with a 2.6.2 kernel with alsa running from the kernel. The sound works when I am logged in as root but when I try logging in as user I get the following message:Sound server informational message:

Informational-artsmessage

Error while initializing the sound driver:
device: default can't be opened for playback (Permission denied)
The sound server will continue, using the null output device.

I should also probably say that I have configured kde not to autodetect the sound device but to use alsa since my oss is broken. This seems to be a permission problem where I need to probably add execute rights for user to use the sound device. Exactly what file should I add this rights to or is something else wrong? Thanks for the help.

should be good to know wich kind of sound board you have....
anyway the problem concerns to the device ...

/dev/"something" need to be free ...

chmod 777 /dev/dsp* /dev/pcm* and other things that can be somehow related to mixer ou media...

Regards

Sorry about that I should have posted my device information. I have a Toshiba 5105 laptop with the i810 chipset. I have also tried the two commands above. Doesn't help. Any other suggestions.

Is there a particular device in the error output message? I had problems too sound wise with the 2.6 that I managed to resolve but not usb so still on 2.4

The problem is the sound is fine when i am logged in as root so I don't see this is a hardware issue. When I log in as a user kde simply gives me the above message without any other information. If this has anything to do with it I created the users using the standard slackware script /usr/sbin/adduser and I might have to add sound permissions somehow. The problem should be solved by adding permissions to a certain file but I have added more permissions to more files in /dev/ that seem to be related to sound then I like. So I guess I am looking for a list of files I should add permission to for a regular user. Thanks for the help.

Update: Sorry for taking everyones time the solution is posted in this thread if anyone is interested:

Don't know how I missed it in the initial search. Thanks again for all the help.

Extremely common problem.

As root, adduser {your username} audio

logout login.

Should do it.
