Thema: problem AUDIO on terrestre channels on atv

hi all, on dinobot 4k + sound is off on most of the channels. I've noticed this issue only with open ATV 6.2 and 6.3 but not with 6.1.
Also, I have the sound problem only with the tuner DVB TC2 on TNT channel. Sat channels and IPTV are working fine. If anyone have any suggestions on how to resolve this problem please let me know.

hi all,
