Installing the wrapper only writes one file to a Kodi setup directory affecting calling an external player when video is played in Kodi, it wouldn't make any difference to nav sounds in Kodi.
Denon A1SE is a fairly old AV amp. I don't think it has HDMI inputs. So you're using SPDIF? In your opening post you said you were using a Panasonic Viera Plasma, how was this connected to the Q10 Pro?
For the Denon connected via SPDIF playback settings should be 'HDMI Output: Close', 'SPDIF Output: RAW', 'HBR Output: RAW5.1'. If you play a simple video file (e.g. 1080p DTS or AC3) through the HiMedia app (Home - Media Center) do you get sound?
For the Pansonic TV, set the playback option to 'HDMI Output: LPCM'. If you play a simple video file (e.g. 1080p DTS or AC3) through the HiMedia app (Home - Media Center) do you get sound?
