Well, for starters, you should see when you highlight it, a indication that it is Working. Then in properties, notice the jack setup . Tells you where you should be plugged in at. That is in gerneral Tab under Controller Information, properties, Then you of course want to make sure it is in fact Enabled. Then in the other tabs, you can test them and get proper settings . A matter of poking around, i do not use that as my default and have good sound , so i am not going to enable mine and play with anything. I am playing around with bbcode . as you can tell.. LOL . experimenting .
