Comment 24 for bug 537703

Hello all. This bug is still present in Compiz 0.9.11.

I did come across a workaround if you're using pulseaudio which worked for me.

Append these two lines:

load-sample-lazy bell /usr/share/sounds/freedesktop/stereo/bell.oga
load-module module-x11-bell sample=bell

To your /etc/pulse/default.pa file and then restart pulseaudio, It restores the system bell for me.
