Autopilot not disengaging solved - at least for me.

I too had the exact same problem and a number of other issues relating to non functioning sounds, pitot lights not going out gear lever not working and autopilot problems.  I had these problems with the panel WITHOUT the VC per the ACE configurator.  I figured something wasn't loading right so I reset to run with the VC and all of my issues were solved.  I am now going to try to remove the VC again and see if anything is fixed without it now.  If not, I suspect that there is a problem with the non - VC mode not loading some gauges correctly.  Perhaps Captainsim can look into this problem for the next patch.  I hope this helps!  Good Luck!!
