ice cream mission help

I've searched the forum before anyone bashes me...

I found that using the shift key makes the jingle sound, but I don't here it.

I also changed my lshift & rshift for the horn to be "Q". I changed everything back to defaults and still don't hear a jingle???

help would be appreciated as this is getting annoying.

thx in advance.

Ya know... I had that same problem... but it started working by taping quickly. At first I was pounding it with my fist
