I've been running Kodi quite successfully on this machine for years, but with the Omega update, videos play without audio for about 10seconds, then freeze. Sometimes if I wait a while, I see subtitles for the episode while the video is frozen. Music doesn't play either. The interface freezes too, to the point where I have to kill -9 it. Switching from Wayland to Xorg hasn't had an effect.
I tried deleting ~/.kodi and restarting, but nothing changes.
I have some music and videos shared via NFS and haven't had any problems playing those. Kodi has crashed a fair amount since updating to Omega, once immediately after launching Kodi. A lot of the time it was when playing video from YouTube and I've updated that plugin to a beta version and it's been better so far.
