I don't get any sound either.
I also noticed that KidGixxer MobiTV doesn't work on Touch. The reason is that it couldn't create a VARS file when it starts up for some reason. So what I do is to download a Handango 1 day trial version MobiTV and use the same method to crack it as we use on KidGixxer version. It works great.
