Hi; As user I still get event sounds after I have muted everything in alsamixer - volume control. Even stranger, if I go to /usr/share/sounds in File Browser and just focus the cursor (i.e. don't click) on a *.wav event file I get the sound in spite of everything being muted and the files being owned by root (other is set to r). As root user I don't get sounds being played on focus, but I do get sound through Helix even though everything is muted. In both cases the sound has background distortion, which is the main problem I am trying to solve. Is it possible that something is somehow getting loaded before ALSA and taking over the sound system before ALSA has a chance to take control?? Rather than fill this post with data as I did earlier, if someone can help, I will be happy to post any configuration information that might help. Regards Bill
