Universal Dock + iPhone = Output Volume Too Low!
So I just recently bought a universal dock with the remote so I could play songs from my phone thru my stereo and basically just for the remote. The problem is that when I plug in the stereo cable in the line out jack on the dock, the volume is greatly diminished when I play a song, I have to turn it up way too loud for the volume to be acceptable. Also, if I plug the same stereo cable straight to my headphone jack the volume is back to normal, it isn't low anymore. I would really like use the line out jack from the dock instead of the headphone jack. Is there a reason why the dock messes with the iphones output volume?
Please Help!
Thanks
