The scale on my Onkyo 805 is similar to what others (ClubNeon, Listener) have reported. It's not uncommon for me to listen to HDMI sources at -10db and other sources at -25db. I don't consider it particularly loud.

Since your radio and game console sound okay, it must be your sound card. Does it have an optical or coaxial output, or are you using the analog outputs?
