it is not possible to attach files to posts, sorry. Just paste your crashlog into this topic. What is logged in “DEBUG info” in the Max2Play Kodi interface (end of menu)?
Basically, running Squeezelite and Kodi at the same time does not work regardless of which Kodi version is installed. On my test system (with HiFiBerry DAC+, M2P 2.25), I cannot start Squeezelite successfully as long as Kodi (15.1) is running as expected. The other way round, Max2Play automatically stopps Squeezelite when starting Kodi. It works perfectly fine.
