Came here from Reddit as am suffering audio drops from my Xbox series X connected to my 2019 Q70r on firmware, you guessed it 1401. I was among the users Michael Digital's suggestion regarding holding down the power button has helped massively, before i would just "Full shut down" my console to give it all a kick. I too disconnected my soundbar, bought a brand new pricey HDMI 2.1 cable, changed ports and ontop of that i had the issue on my Xbox one X, just as i replaced it so to me that rules out the console being at fault as this issue has appeared on both models. Theres a slither of my mind that is open to it being a MS software issue but as many others are having issues without consoles being involved its pretty likely on Samsung (Shock). I've messaged both Samsung UK and Samsung Help on Twitter, including a link to this forum asking A) if Samsung are even aware of this issue users are facing, and B) are they looking into a fix or know anything. So waiting on any bites from that, these days i tend to avoid calling them where possible as have never had any joy down that route be it for mobile, tv or promotions. I did a quick search whilst on there and found a post from someone in Canada and the Netherlands regarding 1401, so clearly its a worldwide issue.
Will drop an update IF/when i get a response, helpful or not....
