I have Riva Tuner 2.06, how do you enable it in Riva Tuner? Thanks

Click the icon that looks like a magnifying glass on top of an IC. It's in the low-level menu. There is a plugin you will need to use within the monitoring thing, click the setup button and browse the descriptions until you find it.
