I hate the Party Poker sounds. They stress me out. Full Tilt Poker’s client, on the other hand, has subtle, soothing sounds. Since it looks like we’ll still be able to play online for a little while yet, try replacing the Party sound files with the FTP sounds, or any other wav files of your choosing.
You will most likely find the FTP and Party sound files here:
C:\Program Files\Full Tilt Poker\Waves
Copy the files you want to use into the PartyPoker folder and rename them to correspond with the files you want to replace. I chose addchips.wav, cards_dealing.wav, chimes.wav, and reminder.wav, since these are the most obnoxious and frequently used sounds. Have fun!
