he muted the sound, but did he try tis?
"1: Go to your %appdata%
2: Go to your .Technichlauncher
3: Open up the tekkit folder
4: Open up the Config file
5: In there locate the IC2.cfg file
Step 2: Change the config to turn off your sounds
1: Locate the # Enable sounds (it is located at the bottom of the first section)
soundsEnabled=true
2: Change the soundsEnabled=true into soundsEnabled=false (It is important to write it correctly with capital and none capital etc.)
(There are many ways to change the cfg file but what I did is that I copied it over to a normal not pad document and changed the part and then named it IC2.cfg and replaced it in the folder)
3: Close the folder and open up the tekkit launcher"
