I'm using Lubuntu with all system sounds disabled. But whenever a popup shows up Code::Blocks it's accompanied with an annoying "bubble pop" sound. Most often this happens when you press "replace all" and a messagebox with info icon pops up telling you the number of replaces.
I tried everything I can find on the internet, so the system should be silent. The same kind of messagebox from other programs doesn't produce sound.
It seems CB disregards system settings and plays event sounds anyway, how can I disable this?
