Thanks! That was exactly that – I used 4k resolution on my Vero4K. After changing that to 1080p, sound works fine. Also found the same issue reported here: Audio stutter for 1 second every 27 seconds
Weird thing is, before the latest update the audio playback was fine. So either this update changed the resolution to 4k silently, or previous version was working fine on 4k.
Anyway, from user experience point of view, that would be great to show some message when user tries to set resolution to 4k, like “Kodi is not optimized for 4k resolution yet, freezes are possible. Please use 1080p for better experience for now”.
