Make the stringtable.csv file, its not hard. It's an excel spreadsheet on my comp but I think you can make it a text file. Other spreadsheet programmes will probably work too.
The text you want to appear when the sound is played goes in the stringtable. It then appears automatically.
In description.ext
class CfgSounds
{
sounds[] = {};
class civvy12
{
name = "";
sound[] = {"civvy12.ogg", db+60, 1.0};
titles[] =
{
0, $STRM_civvy12
};
};
};
In stringtable.csv:-
(column1) (column two)
STRM_civvy12 Your text here!
