I get the following message when I check "Run with the highest priority (realtime priority)" in the Control Center>Sound system settings : "Impossible to start aRts with realtime priority because artswrapper is missing or disabled". Artswrapper is not missing. If it's disabled how do I enable it? I have tried everything I can find to get my kde system notification sounds to work and nothing has helped. My sound works on everything except this. It's not that big of a deal but I would just like to know why this doesn't work.
