When watching an episode of The Flash last night the audio was off and i had to set the offset to 100ms ahead, but now when i enabled debug to post about it i'm pretty sure the audio was fine. This also happens when i was a few episodes in a playlist the first one will have its audio off but the rest of the episodes play fine it's frustrating but not as bad as the box randomly locking up while browsing my library. Anyway here's the debug from just now playing the same file as last night FhfIy
What makes you think this is a problem with LibreELEC. Where are you getting Flash from? if you are streaming you need to make sure your network is good & the source is good.
