Sound Server problem

garyg007 · 10-25-2008, 09:50 PM

I've just started getting an error box with this message:

Quote:

device /dev/dsp can't be opened (Permission denied) The sound server will continue, using the null output device.

It was working previously; I have just finished installing VirtualBox; before that the error was not received. VBox was installed using the current slackware 12.1 slackbuilds.

What I am asking is, what permissions got screwed up, and what do I need to do to fix it?

Any assistance appreciated

I've seen this happen and often the problem is a stale artsd process that won't terminate.

For starters:

Exit KDE/X.

Run ps ax | grep arts. Use kill -9 to kill all such processes.

Verify ALSA remains configured and running okay: Find a wave file and then play using the aplay command (aplay some-wave-file.wav). Any problems then run alsaconf, alsmixer, and alsactl store.

aplay /dev/urandom has a pretty melody and is effective

Thank you for the replies!.

But it looks like something I did when I installed vbox, screwed up the group memberships for my user. Got it fixed after some googling to find out how to look at and change the group memberships.
