FireTV 2 some files not playing after going from 16.2 to 17.3

Hi, I am running a FireTV 2 on the last firmware and have now updated Kodi to Krypton 17.3 I can play some files but others just get stuck on single frames and do not play at all.

I am honestly baffled why some play fine while others not at all.
Any help would truly be appreciated

for the record: I have set audio to:

Channels: 2
Output configuration: Best Match
Resample Quality: Medium
Passthrough enabled: Yes
AC capable Receiver : Yes
Enable AC3 transcoding : No (tried yes too)
Enable DTS audio processing : No

sync playback to display -> No
