got actually an sound issue (disappear) if i change the resulution from 1920x1080 to 3840x2160. At 1920x1080 everything is working fine (video&sound), also the 4k video files in 25hz will be played in 16:9 with any issues - if i raise the output of an 4k file to original size - the movie will be centered and alot of the movie boarder is out of the sceen (resize via an calibrate is not possible).
Also standard movies up to 1920 work fine with Hyperion, only if i start an 4k Video the output for Hyperion is getting green.
Got an RP4i 4gb, thats connected to an Samsung UE75NU8009 - the TV is plugged into the first port (nearest to the USB-C). The same issue is if the RPi4 is connected via an Samsung BluRay Player and this one to the TV.
Got anyone an Idea ?
