I agree with you... I use KDE mostly, so i go into the Control Center and click on Sound and Multimedia section, then System Notifications and click 'apply to all applications' and select 'turn off all' - select 'sounds' then 'apply' ...OK, that stops all system usage of sounds for notifications... sorry! :) Next select 'sound system', (in 'Sound & Multimedia' section again) In the 'General' subsection I'm not networking sound, I have 'highest priority' checked and 4096 sound buffer. In the Hardware subsection I've checked none of these... so there is nothing out of the ordinary, no full duplex (which is a cpu hog) no special sampling rate, nada... If you had to change something, hit 'apply' and that should be it. It usually restarts the alsa system if you changed anything. So, now nothing is calling on /dev/snd unless you have told it to do so. I think that, with the upgrades, stuff gets overwritten. I hope this helps, Ric
