Kodi 17 Tonaussetzer bei MKV File

Hallo,
ich habe ein Problem beim Abspielen einer MKV Datei. Es kommen in unterschiedlichen Abständen Tonaussetzer. Wenn ich BD Isos abspiele funktioniert alles wunderbar. Braucht Kodi noch einen Codec?
Kodi läuft bei mir auf einen Intel NUC und ist per HDMI passthrough an einen Yamaha AVR angeschlossen.

Nebenbei: warum kann ich keine Bilduploads machen? Wollte ein jpg Screenshot anfügen und es kommt folgende Meldung:

Beim Hochladen der Datei ist ein unbekannter Fehler aufgetreten.

Es ist ein Intel NUC i3-6400 mit 8GB Arbeitsspeicher mit Windows10
Kodi 17.0-Beta7 Git:20161219
Da ich keine Dateien anhängen kann ist hier der Log:
