For some reason selecting sound system notifications did not take effect until TDE was restarted -- I have never seen that happen before. If that is permanent, we should add a dialog stating that a TDE restart is required like with font anti-aliasing...
You know the routine. File a bug report. That is the only way anything gets tracked.
Personally, while I admit not understanding the technical details, I don't why Trinity should be restarted for anything. Trinity should reinitialize itself.
