Hello everyone,
TS2 Classic Sound Pack:
Once downloaded the file, decompress it and move the folder "teamspeak_2" which contains the sound files (*.wav) and configuration file (settings.ini) inside the folder "sound" of TeamSpeak 3, for example :
Windows 7 (TS3 win64): C:\Program Files\TeamSpeak 3 Client\sound\teamspeak_2\ (*.wav - *.ini)
Windows 7 (TS3 win32): C:\Program Files (x86)\TeamSpeak 3 Client\sound\teamspeak_2\ (*.wav - *.ini)
Then in the top menu of TeamSpeak going to Settings => Options => Notifications => in the dropdown menu Sound Pack => select "TS2 Classic" => OK button and Done! No need to restart the TS for the change to take effect.
Greetings and excuse my bad English
