Apple TV 4. Audio problem with kodi

First time I experience this problem with audio and I’m sure it’s about what version of kodi
I’m having kodi 17. And just after I started forwarding a movie the sound became weak. Even if hit volume plus. Almost I heard nothing . I did fresh. Start kodi and instal add ons again. Nothing .

The only thing to solve. The problem is delete kodi and re install it again

What is the problem then ? Anything I should know in future to correct the problem without reinstalling kodi again. Becuz the sound is affected only within kodi only

God bless
