Please describe your issue in as much detail as possible:

In KDE konsole there is a terminal bell character. With konsole profile settings set to system bell or system notifications, it is silent. Visual bell will flash the screen, so it does receive the input, but otherwise does not pipe it to sound settings.

Steps for reproducing this issue:

1. Edit konsole profile terminal bell mode to visual bell and enter printf '\a'
2. Edit konsole profile terminal bell mode to system notifications and enter printf '\a'
3. Edit konsole profile terminal bell mode to system bell and enter printf '\a'

Reproduce this in KDE Konsole on SteamOS using the profile's visual bell, system notifications, and system bell settings, then run printf '\a' for each mode. Compare the visual response with the absence of audio and trace how the terminal bell reaches SteamOS sound or notification handling. Done means system bell and system notifications produce an audible result while visual bell still flashes the screen.
