I recently purchased a V1. So far so good. However, after wiring it after diagram #2 I noticed something odd. The sound is coming out of the V1 rather than the remote audio adapter. While the audio adapter does turn the V1 on, it does not change the volume, the V1 itself does. I can change modes on the audio adapter by holding down the button, but thats about it... Does this sound right to you guys?
