 Here is the log:

The Dolby+ audio issue appears at 22:14:25.803 T:140377956149376
Previous file with DTSHDMA7.1 played fine
The "Remote comm. server failed to start" message issue happend as well. I just don't recognize it in the log.

Try adding the "wait for network" setting - your WiFi network IP address is being assigned as Kodi is starting which will cause problems for Kodi when it tries to access your network.

As for the audio issues, a debug log (wiki) provides more useful information and is what we mean by a "log" around here...
