In FC4's gnome-terminal, I don't have any audible bell anymore. Worked before in FC1. Changing the "Terminal bell" option in the profile doesn't change anything. In Preferences=>Sound=>System Bell the option "Sound on audible bell" is selected, toggling it doesn't change anything. Activating visual bell ("visual feedback") works, so the trigger is there.
I reported this already in bug #160774. From the discussion in bug #123927, I had expected this to be fixed in FC4.
Confirmed. Loading pcspkr modules manually fixes it. The only thing "fixed" in bug #123927 is that infrastructure exists now for manually loading module stuff. No fix for pcspkr. *** This bug has been marked as a duplicate of 160774 ***
