Q: How do I get rid of the “Sound not found” notifications?

This notification means a strategy or core asks for a sound that is not in the terminal's sounds folder, so ding1 plays instead. Put a WAV with exactly that name into the folder (for a sound chosen by number, a file “number_name.wav”) and click “Refresh” on the “Trade sounds” page: after that the warning for this sound no longer appears.
