Hi.TV 65" OLED S90D 4K Smart TV (2024) [QE65S90DAUXRU]. Sometimes there is a problem with the sound. The sound becomes very quiet, like from a barrel, and volume control does not affect it in any way. This does not happen during viewing, but after turning on the TV from sleep mode. Only disconnecting from the power supply helps. After turning on, everything works until the next time. The problem occurs somewhere once every 5-7 days. Software version - Version 1201. I found another description of the same problem here https://www.reddit.com/r/OLED/comments/1fuz7ad/samsung_s90d_audio_issue/
