I wanted to watch a movie yesterday with DTS 5.1 audio. But the audio was out of sync. I then tried playing via the TV (LG C7 OLED) and it was perfect. I tried other titles but audio seemed good. I could not find any option to sync audio by +/- like other players.
Are you connected direct into TV or through a receiver? If through a receiver you might have to tweak audio delay there. Also ensure your TV is running latest firmware. There were audio sync issues with this TV that were fixed in firmware updates.
Connected through reciever yes. But other movies seems OK. But why not add a simple +/- sync feature like other players?
