I have RPi2 and I’ve jsut updated OSMC to the newest version (with KODI 15). I’ve noticed, that most of my MKV videos lost sound when using OMXPlayer and with MMAL player, refresh rate adjustment enabled and audio playback sync enabled the movies started to stutter and overall playback is incredibly slow. For now safe setting for me seems to be MMAL player with only refresh rate sync enabled, allthough I’m afraid that without audio resampling enabled the sound will increasingly go out of sync with 23.9fps, but I’ll have to test that. All in all, the settings working on previous version are causing problem with the newest update. Can You take a look at this issue and tell me what is going on and (if that is the case) what am I doing wrong. Thanks!
Unfortunately it turned out that MMAL Player is causing the image to freeze after some time. Curious thing with OMXPlayer is, that if the file contains more than one audio streams, only the first stream is ignored. When there is ony one stream, there is no audio at all.
Generally from my point of view this update is totally broken and it would be great if it got repaired.
