One Away also used the regular buzzer until the current SFX automation began in 2013.
Safe Crackers, Blank Check/Check Game, Pick-a-Pair and Five Price Tags (whenever a NO was revealed) once used the foghorn buzzer, but they have all been changed to the regular buzzer (same goes for Danger Price and More or Less).
There was a time when a handful of games used both buzzers interchangeably, mostly during the late 80s and early 90s; the most notable examples were GP games, like Check-Out, Grocery Game, Grand Game and the retired $uper $aver.
Bargain Game still uses the foghorn buzzer whenever it is lost; it and Most Expensive have been known to use the regular buzzer in the past, which does not fit either game at all.
Speaking of no buzzer for time running out in Hot Seat, I remember when this was true for Switcheroo until it was changed near the end of Barker's run as host.
On the unusual side of things, I've heard the foghorn sounded for losses in 1 Right Price, Double Prices, Hi Lo and Money Game (with the first three usually using the regular buzzer, while Money Game uses neither), and the regular buzzer in Lucky $even and Any Number (where the ding and losing horns are used instead).
