Amazon Prime Video not playing audio on Roku Soundbar
I have my soundbar setup using the HDMI-ARC on my Samsung SmartTV. Everything is working normally until I try to play anything from Amazon Prime Video which results in no sound at all. Even the sound of the volume up or down chime will not play as soon as a Prime Video starts. Video is fine, but audio is non-existent. Other apps like Netflix and Hulu are working without any issue. I have already tried removing Prime Video and re-installing but the issue is still there. I also reset the sound settings to normal and removed any sound leveling or speech clarity but that didn't help. Has anyone had this issue or have a fix?
