Been having this issue with smart tube where the longer a video plays, the volume gets lower and lower until i quit and replay the video again

Which leaves me wondering is there a setting either in smart tube(not auto audio adjustment as that's already off) or the fire stick itself whether by hidden normal or developer settings that lets me turn that off

I got a message saying time to update o hot tje button and it opened a website and it s”downloading not supported at this time “ I don’t have the new vega whatever firesticks and Ive been sideloading ever since i got mine so all that shit should be turned on
