Interesting. The reason I said it that was because I got the impression that auto was the factory setting. At least that’s how I undertone guys that were reporting about it. However I was very sick and my brain function could have been even less than normal!
I also read about some reported that it being turned on by itself with Dolby signal. I have no idea what happened to those people. If you go to the menu, press set defaults, it would set loudness management to "ON" and Dynamic compression to "OFF". I have never seen it changed to "Auto", after playing many Dolby stuff, disc, or digital files...
Now, the owner'a manual is confusing as it says:
See the confusing part in the second bullet. That's why I ran some test with Dolby disc/files, again, have never seen it changed to "Auto" from "Off" automatically. Would you please try it too and see what happens, if you have some spare time?
