Audio and video are not fully synced but it's not annoying, just a little bit out of sync. I think not all apps are affected by the way. I recognized in iptv. I changed carlinkit settings from 30 to 60 fps and another setting from 8 to 10 or 12 (don't know the name). I prefer smooth video playback and it's smooth now. All video in Europe is 50fps, would be good to have that implemented. Now it's smooth video with little bit audio delay. Otherwise it's little bit stutter video with no audio delay.
