not to step on JohnWPB toes, i was a little lazy so i was just gonna wait for you to post your files, but then i got bored, and this is so simple to do, it only takes a few min to knock it out.
toggle ding sound on/off
Add this to ExecTBL.ini
unzip the attached files in to the same dir as RoadRunner.
toggleding.exe should be in the same dir as Road Runner.exe (no sub folders)
Add to RR.ini (optional, this will get added the first time you run the tool)
"BYVAR;igding;=DING OFF<<=DING ON"
This should give you one button that will toggle the feature. Its pretty much the exact same thing as what JohnWPB did, except i think he used 2 buttons one for on one for off and my version is a toggle button.
source au3 file included.
