Query: Not good enough

The sound at medium to high volume was fine. At 35% of volume or lower on my Onkyo receiver the auto detect didn't work. If I turned the volume up, auto detect would pick up the signal. When I turned the amp down it would shut off within a minute or two. I tried it with multiple movies and types of music and it never work at 35 or lower. I had to return it.
