Yes, I've experienced this exact issue with my AVR-254 several times (which, operationally, is nearly identical (but lacking dolby volume))
In every case, the issue was the audio stream was 2.0 or 2.1 DD. The Music, movie, and game modes were all set to Logic 7 (default and/or what I myself left it from last use).
Since Logic 7 post-process on anything but analog 2.0 or 2.0 PCM is unavailable with the 16/26/3600 (or any other HK receiver below the flagships or top-lines (e.g. 7550, 745, 645)) the receiver defaulted to the AUTO surround mode which was just the native source content, leaving 2 channel stereo and DVS the only options. The firmware would not let me go to the other shaded-out modes to select a different surround mode than L7.
To get around this, I have to stop the source such that the audio stream is interrupted/no signal, then go to the "Surround" mode menu and change the surround mode to PLII/PLIIx for the default 'movie' surround mode. (or sub 'Music' or 'Game' as needed)
After which I could select the Movie mode for PLII 5.1 with the incoming 2.0 or 2.1 DD stream.
Give it a try, hope this helps!
