Audio lag when arylic connected to tv with hdmi arc

Hello
I experience audio lag , when arylic h50 is connected to tv with hdmi arc. Tv settings is set to pcm ( it is a Philips tv, pcm setting is called Easy-link). I have used different hdmi arc ports, made a factory reset, tried any setting on tv, but audio latency persist. Every now and then audio/video are in sync, but audio lag will return again after tv and h50 have been turned off and on again. Any solutions?
Best regards

I got a H50 and got the same problem. In fact I got worst because it’s unsync even with the optical input and the line input if I start playing on HDMI mode, if I switch it stay unsync. Anyone have a solution?
Thanks
