Kodi crashes with this:
May 19 16:55:03 osmc mediacenter[2967]: /usr/lib/kodi/kodi.bin: symbol lookup error: /usr/osmc/lib/libamcodec.so: undefined symbol: audio_decode_stop
We don’t know where this symbol comes from. It is not introduced by OSMC.
I suggest reinstalling OSMC. This will definitely solve your problem.
