Sound Glitchy in MDK 9.1
 

Newbie Using Mandrake 9.1:

When I log into mandrake 9 I got this message in a popup:

"Sound Server Message:
Can't set real-time scheduling priority.
You need to run artswrapper as root or setuid root. This means that you will lickly not be able to produce acceptable sounds (ie without clicks and breaks) "

And the message is exactly right.. my sounds works fine when I am playing mp3s, but when I am in games (Zsnes and TuxRacer) the sound is slighty off and 'clicky'

When I log into root and attempt to run "artswrapper" I get this error:
>> running as realtime process now (priority 50)
Error while initializing the sound driver:
device /dev/dsp can't be opened (Device or resource busy)


Anyone have any clue what I need to do? What is artswrapper? I guessing I need sound drivers... but my sound it built into my motherboard which I have no idea what it is. Any advice would be great.

Hmmm, that is weird. Starting it a second time might be why it states that /dev/dsp is busy, the artserver running as the regular user (weird) already has the device busy. I shut the aRTs sounderver off, and went back to OSS Driver with xmms. I have no problem with any app except k3b to play songs before burning (it only works with arts server). I didn't like the flaky operation of arts. Under Redhat, Preferences-->Sound-->Sound Server, there is an option that I unselected that 'start the arts sounderver on KDE start'. You might try that. That option is somewhere in configDrake, Preferences, somewhere.

P.S. If you needed the sound drivers, you wouldn't hear anything. The drivers are fine, the sound server is not behaving.

do the latter. open a terminal window, become root and then do
chmod +s /usr/bin/artswrapper

Log out and log in again. You should stop getting that message.
